Commit d469647baf ("Input: simplify event handling logic") introduced
code that would set handler->events() method to either
input_handler_events_filter() or input_handler_events_default() or
input_handler_events_null(), depending on the kind of input handler
(a filter or a regular one) we are dealing with. Unfortunately this
breaks cases when we try to re-register the same filter (as is the case
with sysrq handler): after initial registration the handler will have 2
event handling methods defined, and will run afoul of the check in
input_handler_check_methods():
input: input_handler_check_methods: only one event processing method can be defined (sysrq)
sysrq: Failed to register input handler, error -22
Fix this by adding handle_events() method to input_handle structure and
setting it up when registering a new input handle according to event
handling methods defined in associated input_handler structure, thus
avoiding modifying the input_handler structure.

Current dev_loss_tmo handling checks whether there has been a previous
call to unregister with SCSI transport. If so, the NDLP kref count is
decremented a second time in dev_loss_tmo as the final kref release.
However, this can sometimes result in a reference count underflow if
there is also a race to unregister with NVMe transport as well. Add a
check for NVMe transport registration before decrementing the final
kref. If NVMe transport is still registered, then the NVMe transport
unregistration is designated as the final kref decrement.

WriteBooster improves write speeds by enabling a pseudo SLC cache. Using
the 'fio seqwrite' test we can achieve speeds of 945MB/s with this
feature enabled (until the cache is exhausted) before dropping back to
~260MB/s (which are the speeds we see without the WriteBooster feature

Assuming the UFSHCD_CAP_WB_EN capability is set by the host then
WriteBooster can also be enabled and disabled via sysfs so it is

We have two reports of failed memory allocation in btrfs' code which is
calling into report zones.
Both of these reports have the following signature coming from
__vmalloc_area_node():
kworker/u17:5: vmalloc error: size 0, failed to allocate pages, mode:0x10dc2(GFP_KERNEL|__GFP_HIGHMEM|__GFP_NORETRY|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0
Further debugging showed these where allocations of one sector (512
bytes) and at least one of the reporter's systems where low on memory,
so going through the overhead of allocating a vm area failed.
Switching the allocation from __vmalloc() to kvzalloc() avoids the
overhead of vmalloc() on small allocations and succeeds.
Note: the buffer is already freed using kvfree() so there's no need to
adjust the free path.

A new hybrid poll is implemented on the io_uring layer. Once an IO is
issued, it will not poll immediately, but rather block first and re-run
before IO complete, then poll to reap IO. While this poll method could
be a suboptimal solution when running on a single thread, it offers
performance lower than regular polling but higher than IRQ, and CPU
utilization is also lower than polling.
To use hybrid polling, the ring must be setup with both the
IORING_SETUP_IOPOLL and IORING_SETUP_HYBRID)IOPOLL flags set. Hybrid
polling has the same restrictions as IOPOLL, in that commands must
explicitly support it.

then entries designated by offset + nr buffers will be replaced if they
already exist.

Work in progress, but get rid of the per-ring serialization of resource
nodes, like registered buffers and files. Main issue here is that one
node can otherwise hold up a bunch of other nodes from getting freed,
which is especially a problem for file resource nodes and networked
workloads where some descriptors may not see activity in a long time.
As an example, instantiate an io_uring ring fd and create a sparse
registered file table. Even 2 will do. Then create a socket and register
it as fixed file 0, F0. The number of open files in the app is now 5,
with 0/1/2 being the usual stdin/out/err, 3 being the ring fd, and 4
being the socket. Register this socket (eg "the listener") in slot 0 of
the registered file table. Now add an operation on the socket that uses
slot 0. Finally, loop N times, where each loop creates a new socket,
registers said socket as a file, then unregisters the socket, and
finally closes the socket. This is roughly similar to what a basic
accept loop would look like.
At the end of this loop, it's not unreasonable to expect that there
would still be 5 open files. Each socket created and registered in the
loop is also unregistered and closed. But since the listener socket
registered first still has references to its resource node due to still
being active, each subsequent socket unregistration is stuck behind it
for reclaim. Hence 5 + N files are still open at that point, where N is
awaiting the final put held up by the listener socket.
Rewrite the io_rsrc_node handling to NOT rely on serialization. Struct
io_kiocb now gets explicit resource nodes assigned, with each holding a
reference to the parent node. A parent node is either of type FILE or
BUFFER, which are the two types of nodes that exist. A request can have
two nodes assigned, if it's using both registered files and buffers.
Since request issue and task_work completion is both under the ring
private lock, no atomics are needed to handle these references. It's a
simple unlocked inc/dec. As before, the registered buffer or file table
each hold a reference as well to the registered nodes. Final put of the
node will remove the node and free the underlying resource, eg unmap the
buffer or put the file.
Outside of removing the stall in resource reclaim described above, it
has the following advantages:
1) It's a lot simpler than the previous scheme, and easier to follow.
No need to specific quiesce handling anymore.
2) There are no resource node allocations in the fast path, all of that
happens at resource registration time.
3) The structs related to resource handling can all get simplified
quite a bit, like io_rsrc_node and io_rsrc_data. io_rsrc_put can
go away completely.
4) Handling of resource tags is much simpler, and doesn't require
persistent storage as it can simply get assigned up front at
registration time. Just copy them in one-by-one at registration time
and assign to the resource node.
The only real downside is that a request is now explicitly limited to
pinning 2 resources, one file and one buffer, where before just
assigning a resource node to a request would pin all of them. The upside
is that it's easier to follow now, as an individual resource is
explicitly referenced and assigned to the request.
With this in place, the above mentioned example will be using exactly 5
files at the end of the loop, not N.

Currently, if 'Global IRQ' is supported by the platform, only the Link up
interrupt is enabled in the PARF_INT_ALL_MASK register. This masks MSIs
on some platforms. The MSI bits in PARF_INT_ALL_MASK register are enabled
by default in the hardware, but commit 4581403f67 ("PCI: qcom: Enumerate
endpoints based on Link up event in 'global_irq' interrupt") disabled them
and enabled only the Link up interrupt. While MSI continued to work on the
SM8450 platform that was used to test the offending commit, on other
platforms like SM8250, X1E80100, MSIs are getting masked. And they require
enabling the MSI interrupt bits in the register to unmask (enable) the
MSIs.
Even though the MSI interrupt enable bits in PARF_INT_ALL_MASK are
described as 'diagnostic' interrupts in the internal documentation,
disabling them masks MSI on these platforms. Due to this, MSIs were not
reported to be received these platforms while supporting 'Global IRQ'.
So, enable the MSI interrupts along with the Link up interrupt in the
PARF_INT_ALL_MASK register if 'Global IRQ' is supported. This ensures that
the MSIs continue to work and also the driver is able to catch the Link
up interrupt for enumerating endpoint devices.

In the fwnode_iio_channel_get_by_name(), iterating over parent nodes to
acquire IIO channels via fwnode_for_each_parent_node(). The variable
chan was mistakenly attempted on the original node instead of the
current parent node. This patch corrects the logic to ensure that
__fwnode_iio_channel_get_by_name() is called with the correct parent
node.

On the Qualcomm SAR2130P platform the PCIe host is compatible with the
DWC controller present on the SM8550 platorm, just using one additional
clock.
