Pull erofs updates from Gao Xiang:
"We now support metadata compression. It can be useful for embedded use
cases or archiving a large number of small files.
Additionally, readdir performance has been improved by enabling
readahead (note that it was already common practice for ext3/4 non-dx
and f2fs directories). We may consider further improvements later to
align with ext4's s_inode_readahead_blks behavior for slow devices
too.
The remaining commits are minor.
Summary:
- Add support for metadata compression
- Enable readahead for directories to improve readdir performance
- Minor fixes and cleanups"

Pull btrfs updates from David Sterba:
"A number of usability and feature updates, scattered performance
improvements and fixes. Highlight of the core changes is getting
closer to enabling large folios (now behind a config option).
User visible changes:
- update defrag ioctl, add new flag to request no compression on
existing extents
- restrict writes to block devices after mount
- in experimental config, enable large folios for data, almost
complete but not widely tested
- add stats tracking duration of critical section in transaction
commit to /sys/fs/btrfs/FSID/commit_stats
Performance improvements:
- caching of lookup results of free space bitmap (20% runtime
improvement on an empty file creation benchmark)
- accessors to metadata (b-tree items) simplified and optimized,
minor improvement in metadata-heavy workloads
- readahead on compressed data improves sequential read
- the xarray for extent buffers is indexed by denser keys, leading to
better packing of the nodes (50-70% reduction of leaf nodes)
Notable fixes:
- stricter compression mount option parsing
- send properly emits fallocate command for file holes when protocol
v2 is used
- fix overallocation of chunks with mount option 'ssd_spread', due to
interaction with size classes not finding the right chunk
(workaround: manual reclaim by 'usage' balance filter)
- various quota enable/disable races with rescan, more verbose
notifications about inconsistent state
- populate otime in tree-log during log replay
- handle ENOSPC when NOCOW file is used with mmap()
Core:
- large data folios enabled in experimental config
- improved error handling, transaction abort call sites
- in zoned mode, allocate reloc block group on mount to make sure
there's always one available for zone reclaim under heavy load
- rework device opening, they're always open as read-only and delayed
until the super block is created, allowing the restricted writes
after mount
- preparatory work for adding blk_holder_ops, allowing device
freeze/thaw in the future
Cleanups, refactoring:
- type and naming unifications (int/bool, return variables)
- rb-tree helper refactoring and simplifications
- reorder memory allocations to less critical places
- RCU string (used for device name) refactoring and API removal
- replace all remaining use of strcpy()"

When viommu type is IOMMU_VIOMMU_TYPE_ARM_SMMUV3, always return or init the
standard struct arm_vsmmu, instead of going through impl_ops that must have
its own viommu type than the standard IOMMU_VIOMMU_TYPE_ARM_SMMUV3.
Given that arm_vsmmu_init() is called after arm_smmu_get_viommu_size(), any
unsupported viommu->type must be a corruption. And it must be a driver bug
that its vsmmu_size and vsmmu_init ops aren't paired. Warn these two cases.

Argument 'p' of reactors_show() and monitor_reactor_show() is not a pointer
to struct rv_reactor, it is actually a pointer to the list_head inside
struct rv_reactor. Therefore it's wrong to cast 'p' to struct rv_reactor *.
This wrong type cast has been there since the beginning. But it still
worked because the list_head was the first field in struct rv_reactor_def.
This is no longer true since commit 3d3c376118 ("rv: Merge struct
rv_reactor_def into struct rv_reactor") moved the list_head, and this wrong
type cast became a functional problem.

The MediaTek implementation of the sbsa_gwdt watchdog has a race
condition where a write to SBSA_GWDT_WRR is ignored if it occurs while
the hardware is processing a timeout refresh that asserts WS0.
Detect this based on the hardware implementer and adjust
wdd->min_hw_heartbeat_ms to avoid the race by forcing the keepalive ping
to be one second later.

During communication with Focusrite Scarlett Gen 2/3/4 USB audio
interfaces, -EPROTO is sometimes returned from scarlett2_usb_tx(),
snd_usb_ctl_msg() which can cause initialisation and control
operations to fail intermittently.
This patch adds up to 5 retries in scarlett2_usb(), with a delay
starting at 5ms and doubling each time. This follows the same approach
as the fix for usb_set_interface() in endpoint.c (commit f406005e16
("ALSA: usb-audio: Add retry on -EPROTO from usb_set_interface()")),
which resolved similar -EPROTO issues during device initialisation,
and is the same approach as in fcp.c:fcp_usb().

Before commit df6d7277e5 ("i2c: core: Do not dereference fwnode in struct
device"), i2c_unregister_device() only called fwnode_handle_put() on
of_node-s in the form of calling of_node_put(client->dev.of_node).
But after this commit the i2c_client's fwnode now unconditionally gets
fwnode_handle_put() on it.
When the i2c_client has no primary (ACPI / OF) fwnode but it does have
a software fwnode, the software-node will be the primary node and
fwnode_handle_put() will put() it.
But for the software fwnode device_remove_software_node() will also put()
it leading to a double free:

Add support for the Texas Instruments INA228 Ultra-Precise
Power/Energy/Charge Monitor.
The INA228 is very similar to the INA238 but offers four bits of extra
precision in the temperature, voltage and current measurement fields.
It also supports energy and charge monitoring, the latter of which is
not supported through this patch.
While it seems in the datasheet that some constants such as LSB values
differ between the 228 and the 238, they differ only for those registers
where four bits of precision have been added and they differ by a factor
of 16 (VBUS, VSHUNT, DIETEMP, CURRENT).
Therefore, the INA238 constants are still applicable with regard
to the bit of the same significance.

SMB1 already supports querying reparse points and detecting types of
symlink, fifo, socket, block and char.
This change implements the missing part - ability to create a new reparse
points over SMB1. This includes everything which SMB2+ already supports:
- native SMB symlinks and sockets
- NFS style of special files (symlinks, fifos, sockets, char/block devs)
- WSL style of special files (symlinks, fifos, sockets, char/block devs)
Attaching a reparse point to an existing file or directory is done via
SMB1 SMB_COM_NT_TRANSACT/NT_TRANSACT_IOCTL/FSCTL_SET_REPARSE_POINT command
and implemented in a new cifs_create_reparse_inode() function.
This change introduce a new callback ->create_reparse_inode() which creates
a new reperse point file or directory and returns inode. For SMB1 it is
provided via that new cifs_create_reparse_inode() function.
Existing reparse.c code was only slightly updated to call new protocol
callback ->create_reparse_inode() instead of hardcoded SMB2+ function.
This make the whole reparse.c code to work with every SMB dialect.
The original callback ->create_reparse_symlink() is not needed anymore as
the implementation of new create_reparse_symlink() function is dialect
agnostic too. So the link.c code was updated to call that function directly
(and not via callback).

When not searching for child entries with msearch wildcard pattern then ask
server just for one output entry. There is no need to ask for more entries
as we are interested only for one search result, as we are doing query on
path.
CIFSFindFirst() with msearch=false is called by the cifs_query_path_info()
function.
