Pull io_uring updates from Jens Axboe:
"A mix of fixes and a few stragglers. In detail:
- Revert the bogus __read_mostly that we discussed for the initial
pull request.
- Fix a merge window regression with fixed file registration error
path handling.
- Fix io-wq numa node affinities.
- Series abstracting out an io_identity struct, making it both easier
to see what the personality items are, and also easier to to adopt
more. Use this to cover audit logging.
- Fix for read-ahead disabled block condition in async buffered
reads, and using single page read-ahead to unify what
generic_file_buffer_read() path is used.
- Series for REQ_F_COMP_LOCKED fix and removal of it (Pavel)
- Poll fix (Pavel)"

xen/events: block rogue events for some time
In order to avoid high dom0 load due to rogue guests sending events at high frequency, block those events in case there was no action needed in dom0 to handle the events. This is done by adding a per-event counter, which set to zero in case an EOI without the XEN_EOI_FLAG_SPURIOUS is received from a backend driver, and incremented when this flag has been set. In case the counter is 2 or higher delay the EOI by 1 << (cnt - 2) jiffies, but not more than 1 second. In order not to waste memory shorten the per-event refcnt to two bytes (it should normally never exceed a value of 2). Add an overflow check to evtchn_get() to make sure the 2 bytes really won't overflow. This is part of XSA-332.

xen/events: defer eoi in case of excessive number of events
In case rogue guests are sending events at high frequency it might happen that xen_evtchn_do_upcall() won't stop processing events in dom0. As this is done in irq handling a crash might be the result. In order to avoid that, delay further inter-domain events after some time in xen_evtchn_do_upcall() by forcing eoi processing into a worker on the same cpu, thus inhibiting new events coming in. The time after which eoi processing is to be delayed is configurable via a new module parameter "event_loop_timeout" which specifies the maximum event loop time in jiffies (default: 2, the value was chosen after some tests showing that a value of 2 was the lowest with an only slight drop of dom0 network throughput while multiple guests performed an event storm). How long eoi processing will be delayed can be specified via another parameter "event_eoi_delay" (again in jiffies, default 10, again the value was chosen after testing with different delay values). This is part of XSA-332.

xen/pciback: use lateeoi irq binding
In order to reduce the chance for the system becoming unresponsive due to event storms triggered by a misbehaving pcifront use the lateeoi irq binding for pciback and unmask the event channel only just before leaving the event handling function. Restructure the handling to support that scheme. Basically an event can come in for two reasons: either a normal request for a pciback action, which is handled in a worker, or in case the guest has finished an AER request which was requested by pciback. When an AER request is issued to the guest and a normal pciback action is currently active issue an EOI early in order to be able to receive another event when the AER request has been finished by the guest. Let the worker processing the normal requests run until no further request is pending, instead of starting a new worker ion that case. Issue the EOI only just before leaving the worker. This scheme allows to drop calling the generic function xen_pcibk_test_and_schedule_op() after processing of any request as the handling of both request types is now separated more cleanly.

xen/pvcallsback: use lateeoi irq binding
In order to reduce the chance for the system becoming unresponsive due to event storms triggered by a misbehaving pvcallsfront use the lateeoi irq binding for pvcallsback and unmask the event channel only after handling all write requests, which are the ones coming in via an irq.

In order to reduce the chance for the system becoming unresponsive due to event storms triggered by a misbehaving scsifront use the lateeoi irq binding for scsiback and unmask the event channel only just before leaving the event handling function. In case of a ring protocol error don't issue an EOI in order to avoid the possibility to use that for producing an event storm. This at once will result in no further call of scsiback_irq_fn(), so the ring_error struct member can be dropped and scsiback_do_cmd_fn() can signal the protocol error via a negative return value.

xen/events: add a new "late EOI" evtchn framework
In order to avoid tight event channel related IRQ loops add a new framework of "late EOI" handling: the IRQ the event channel is bound to will be masked until the event has been handled and the related driver is capable to handle another event. The driver is responsible for unmasking the event channel via the new function xen_irq_lateeoi(). This is similar to binding an event channel to a threaded IRQ, but without having to structure the driver accordingly. In order to support a future special handling in case a rogue guest is sending lots of unsolicited events, add a flag to xen_irq_lateeoi() which can be set by the caller to indicate the event was a spurious one.

xen/events: add a proper barrier to 2-level uevent unmasking
A follow-up patch will require certain write to happen before an event channel is unmasked. While the memory barrier is not strictly necessary for all the callers, the main one will need it. In order to avoid an extra memory barrier when using fifo event channels, mandate evtchn_unmask() to provide write ordering. The 2-level event handling unmask operation is missing an appropriate barrier, so add it. Fifo event channels are fine in this regard due to using sync_cmpxchg(). This is part of XSA-332.

xen/events: avoid removing an event channel while handling it
Today it can happen that an event channel is being removed from the system while the event handling loop is active. This can lead to a race resulting in crashes or WARN() splats when trying to access the irq_info structure related to the event channel. Fix this problem by using a rwlock taken as reader in the event handling loop and as writer when deallocating the irq_info structure. As the observed problem was a NULL dereference in evtchn_from_irq() make this function more robust against races by testing the irq_info pointer to be not NULL before dereferencing it. And finally make all accesses to evtchn_to_irq[row][col] atomic ones in order to avoid seeing partial updates of an array element in irq handling. Note that irq handling can be entered only for event channels which have been valid before, so any not populated row isn't a problem in this regard, as rows are only ever added and never removed. This is XSA-331.

It's my first time doing something like this, I haven't included the set_fs stuff because the base branch it depends on hasn't been merged yet.

Recalling the first round of new code for 5.10, in which we added:
- New feature: Widen inode timestamps and quota grace expiration
timestamps to support dates through the year 2486.
- New feature: storing inode btree counts in the AGI to speed up certain
mount time per-AG block reservation operatoins and add a little more
metadata redundancy.
For the second round of new code for 5.10:
- Deprecate the V4 filesystem format, some disused mount options, and some
legacy sysctl knobs now that we can support dates into the 25th century.
Note that removal of V4 support will not happen until the early 2030s.
- Fix some probles with inode realtime flag propagation.
- Fix some buffer handling issues when growing a rt filesystem.
- Fix a problem where a BMAP_REMAP unmap call would free rt extents even
though the purpose of BMAP_REMAP is to avoid freeing the blocks.
- Strengthen the dabtree online scrubber to check hash values on child
dabtree blocks.
- Actually log new intent items created as part of recovering log intent
items.
- Fix a bug where quotas weren't attached to an inode undergoing bmap
intent item recovery.
- Fix a buffer overrun problem with specially crafted log buffer
headers.
- Various cleanups to type usage and slightly inaccurate comments.
- More cleanups to the xattr, log, and quota code.
- Don't run the (slower) shared-rmap operations on attr fork mappings.
- Fix a bug where we failed to check the LSN of finobt blocks during
replay and could therefore overwrite newer data with older data.
- Clean up the ugly nested transaction mess that log recovery uses to
stage intent item recovery in the correct order by creating a proper
data structure to capture recovered chains.
- Use the capture structure to resume intent item chains with the
same log space and block reservations as when they were captured.
- Fix a UAF bug in bmap intent item recovery where we failed to maintain
our reference to the incore inode if the bmap operation needed to
relog itself to continue.
- Rearrange the defer ops mechanism to finish newly created subtasks
of a parent task before moving on to the next parent task.
- Automatically relog intent items in deferred ops chains if doing so
would help us avoid pinning the log tail. This will help fix some
log scaling problems now and will facilitate atomic file updates later.
- Fix a deadlock in the GETFSMAP implementation by using an internal
memory buffer to reduce indirect calls and copies to userspace,
thereby improving its performance by ~20%.
- Fix various problems when calling growfs on a realtime volume would
not fully update the filesystem metadata.
- Fix broken Kconfig asking about deprecated XFS when XFS is disabled.

Merge tag 'xfs-5.10-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull more xfs updates from Darrick Wong:
"The second large pile of new stuff for 5.10, with changes even more
monumental than last week!
We are formally announcing the deprecation of the V4 filesystem format
in 2030. All users must upgrade to the V5 format, which contains
design improvements that greatly strengthen metadata validation,
supports reflink and online fsck, and is the intended vehicle for
handling timestamps past 2038. We're also deprecating the old Irix
behavioral tweaks in September 2025.
Coming along for the ride are two design changes to the deferred
metadata ops subsystem. One of the improvements is to retain correct
logical ordering of tasks and subtasks, which is a more logical design
for upper layers of XFS and will become necessary when we add atomic
file range swaps and commits. The second improvement to deferred ops
improves the scalability of the log by helping the log tail to move
forward during long-running operations. This reduces log contention
when there are a large number of threads trying to run transactions.
In addition to that, this fixes numerous small bugs in log recovery;
refactors logical intent log item recovery to remove the last
remaining place in XFS where we could have nested transactions; fixes
a couple of ways that intent log item recovery could fail in ways that
wouldn't have happened in the regular commit paths; fixes a deadlock
vector in the GETFSMAP implementation (which improves its performance
by 20%); and fixes serious bugs in the realtime growfs, fallocate, and
bitmap handling code.
Summary:
- Deprecate the V4 filesystem format, some disused mount options, and
some legacy sysctl knobs now that we can support dates into the
25th century. Note that removal of V4 support will not happen until
the early 2030s.
- Fix some probles with inode realtime flag propagation.
- Fix some buffer handling issues when growing a rt filesystem.
- Fix a problem where a BMAP_REMAP unmap call would free rt extents
even though the purpose of BMAP_REMAP is to avoid freeing the
blocks.
- Strengthen the dabtree online scrubber to check hash values on
child dabtree blocks.
- Actually log new intent items created as part of recovering log
intent items.
- Fix a bug where quotas weren't attached to an inode undergoing bmap
intent item recovery.
- Fix a buffer overrun problem with specially crafted log buffer
headers.
- Various cleanups to type usage and slightly inaccurate comments.
- More cleanups to the xattr, log, and quota code.
- Don't run the (slower) shared-rmap operations on attr fork
mappings.
- Fix a bug where we failed to check the LSN of finobt blocks during
replay and could therefore overwrite newer data with older data.
- Clean up the ugly nested transaction mess that log recovery uses to
stage intent item recovery in the correct order by creating a
proper data structure to capture recovered chains.
- Use the capture structure to resume intent item chains with the
same log space and block reservations as when they were captured.
- Fix a UAF bug in bmap intent item recovery where we failed to
maintain our reference to the incore inode if the bmap operation
needed to relog itself to continue.
- Rearrange the defer ops mechanism to finish newly created subtasks
of a parent task before moving on to the next parent task.
- Automatically relog intent items in deferred ops chains if doing so
would help us avoid pinning the log tail. This will help fix some
log scaling problems now and will facilitate atomic file updates
later.
- Fix a deadlock in the GETFSMAP implementation by using an internal
memory buffer to reduce indirect calls and copies to userspace,
thereby improving its performance by ~20%.
- Fix various problems when calling growfs on a realtime volume would
not fully update the filesystem metadata.
- Fix broken Kconfig asking about deprecated XFS when XFS is
disabled"

mm: cleanup the gfp_mask handling in __vmalloc_area_node
Patch series "two small vmalloc cleanups". This patch (of 2): __vmalloc_area_node currently has four different gfp_t variables to just express this simple logic: - use the passed in mask, plus __GFP_NOWARN and __GFP_HIGHMEM (if suitable) for the underlying page allocation - use just the reclaim flags from the passed in mask plus __GFP_ZERO for allocating the page array Simplify this down to just use the pre-existing nested_gfp as-is for the page array allocation, and just the passed in gfp_mask for the page allocation, after conditionally ORing __GFP_HIGHMEM into it. This also makes the allocation warning a little more correct. Also initialize two variables at the time of declaration while touching this area.

drm/i915: use vmap in i915_gem_object_map
i915_gem_object_map implements fairly low-level vmap functionality in a driver. Split it into two helpers, one for remapping kernel memory which can use vmap, and one for I/O memory that uses vmap_pfn. The only practical difference is that alloc_vm_area prefeaults the vmalloc area PTEs, which doesn't seem to be required here for the kernel memory case (and could be added to vmap using a flag if actually required).

drm/i915: use vmap in shmem_pin_map
shmem_pin_map somewhat awkwardly reimplements vmap using alloc_vm_area and manual pte setup. The only practical difference is that alloc_vm_area prefeaults the vmalloc area PTEs, which doesn't seem to be required here (and could be added to vmap using a flag if actually required). Switch to use vmap, and use vfree to free both the vmalloc mapping and the page array, as well as dropping the references to each page.
