git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- Split dm-bufio's rw_semaphore and rbtree. Offers improvements to
dm-bufio's locking to allow increased concurrent IO -- particularly
for read access for buffers already in dm-bufio's cache.
- Also split dm-bio-prison-v1's spinlock and rbtree with comparable aim
at improving concurrent IO (for the DM thinp target).
- Both the dm-bufio and dm-bio-prison-v1 scaling of the number of locks
and rbtrees used are managed by dm_num_hash_locks(). And the hash
function used by both is dm_hash_locks_index().
- Allow DM targets to require DISCARD, WRITE_ZEROES and SECURE_ERASE to
be split at the target specified boundary (in terms of
max_discard_sectors, max_write_zeroes_sectors and
max_secure_erase_sectors respectively).
- DM verity error handling fix for check_at_most_once on FEC.
- Update DM verity target to emit audit events on verification failure
and more.
- DM core ->io_hints improvements needed in support of new discard
support that is added to the DM "zero" and "error" targets.
- Fix missing kmem_cache_destroy() call in initialization error path of
both the DM integrity and DM clone targets.
- A couple fixes for DM flakey, also add "error_reads" feature.
- Fix DM core's resume to not lock FS when the DM map is NULL;
otherwise initial table load can race with FS mount that takes
superblock's ->s_umount rw_semaphore.
- Various small improvements to both DM core and DM targets.

Common KVM changes for 6.4:
- Drop unnecessary casts from "void *" throughout kvm_main.c
- Tweak the layout of "struct kvm_mmu_memory_cache" to shrink the struct
size by 8 bytes on 64-bit kernels by utilizing a padding hole
- Fix a documentation format goof that was introduced when the KVM docs
were converted to ReST
- Constify MIPS's internal callbacks (a leftover from the hardware enabling
rework that landed in 6.3)

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 updates for 6.4
- Numerous fixes for the pathological lock inversion issue that
plagued KVM/arm64 since... forever.
- New framework allowing SMCCC-compliant hypercalls to be forwarded
to userspace, hopefully paving the way for some more features
being moved to VMMs rather than be implemented in the kernel.
- Large rework of the timer code to allow a VM-wide offset to be
applied to both virtual and physical counters as well as a
per-timer, per-vcpu offset that complements the global one.
This last part allows the NV timer code to be implemented on
top.
- A small set of fixes to make sure that we don't change anything
affecting the EL1&0 translation regime just after having having
taken an exception to EL2 until we have executed a DSB. This
ensures that speculative walks started in EL1&0 have completed.
- The usual selftest fixes and improvements.

Pull io_uring updates from Jens Axboe:
- Cleanup of the io-wq per-node mapping, notably getting rid of it so
we just have a single io_wq entry per ring (Breno)
- Followup to the above, move accounting to io_wq as well and
completely drop struct io_wqe (Gabriel)
- Enable KASAN for the internal io_uring caches (Breno)
- Add support for multishot timeouts. Some applications use timeouts to
wake someone waiting on completion entries, and this makes it a bit
easier to just have a recurring timer rather than needing to rearm it
every time (David)
- Support archs that have shared cache coloring between userspace and
the kernel, and hence have strict address requirements for mmap'ing
the ring into userspace. This should only be parisc/hppa. (Helge, me)
- XFS has supported O_DIRECT writes without needing to lock the inode
exclusively for a long time, and ext4 now supports it as well. This
is true for the common cases of not extending the file size. Flag the
fs as having that feature, and utilize that to avoid serializing
those writes in io_uring (me)
- Enable completion batching for uring commands (me)
- Revert patch adding io_uring restriction to what can be GUP mapped or
not. This does not belong in io_uring, as io_uring isn't really
special in this regard. Since this is also getting in the way of
cleanups and improvements to the GUP code, get rid of if (me)
- A few series greatly reducing the complexity of registered resources,
like buffers or files. Not only does this clean up the code a lot,
the simplified code is also a LOT more efficient (Pavel)
- Series optimizing how we wait for events and run task_work related to
it (Pavel)
- Fixes for file/buffer unregistration with DEFER_TASKRUN (Pavel)

Pull btrfs updates from David Sterba:
"Mostly core changes and cleanups, some notable fixes and two
performance improvements in directory logging.
The IO path cleanups are removing or refactoring old code, scrub main
loop has been completely rewritten also refactoring old code.
There are some changes to non-btrfs code, mostly trivial, the cgroup
punt bio logic is only moved from generic code.
Performance improvements:
- improve logging changes in a directory during one transaction,
avoid iterating over items and reduce lock contention (fsync time
4x lower)
- when logging directory entries during one transaction, reduce
locking of subvolume trees by checking tree-log instead
(improvement in throughput and latency for concurrent access to a
subvolume)
Notable fixes:
- dev-replace:
- properly honor read mode when requested to avoid reading from
source device
- target device won't be used for eventual read repair, this is
unreliable for NODATASUM files
- when there are unpaired (and unrepairable) metadata during
replace, exit early with error and don't try to finish whole
operation
- scrub ioctl properly rejects unknown flags
- fix global block reserve calculations
- fix partial direct io write when there's a page fault in the
middle, iomap will try to continue with partial request but the
btrfs part did not match that, this can lead to zeros written
instead of data
Core changes:
- io path:
- continued cleanups and refactoring around bio handling
- extent io submit path simplifications and cleanups
- flush write path simplifications and cleanups
- rework logic of passing sync mode of bio, with further cleanups
- rewrite scrub code flow, restructure how the stripes are enumerated
and verified in a more unified way
- allow to set lower threshold for block group reclaim in debug mode
to aid zoned mode testing
- remove obsolete time-based delayed ref throttling logic when
truncating items
- DREW locks are not using percpu variables anymore
- more warning fixes (-Wmaybe-uninitialized)
- u64 division simplifications
- error handling improvements
Non-btrfs code changes:
- push cgroup punt bio logic to btrfs code (there was no other user
of that), the functionality can be now selected separately by
BLK_CGROUP_PUNT_BIO
- crc32c_impl removed after removing last uses in btrfs code
- add btrfs_assertfail() to objtool table"
* tag 'for-6.4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (147 commits)
btrfs: mark btrfs_assertfail() __noreturn

The AXP15060 is a PMIC chip produced by X-Powers, and could be connected
via an I2C bus.
Describe the regmap and the MFD bits, along with the registers exposed
via I2C. Eventually advertise the device using a new compatible string
and add support for power off the system.
The driver would disable PEK function if IRQ is not configured in device
tree, since some boards (For example, Starfive Visionfive 2) didn't
connect IRQ line of PMIC to SOC.
GPIO function isn't enabled in this commit, since its configuration
operation is different from any existing AXP PMICs and needs
logic modification on existing driver. GPIO support might come in later
patches.

the pipe splice actor should attempt to walk past the end of
rq_pages, it needs to terminate the READ operation to prevent
corruption of the pointer addresses in the fields just beyond the
array.
A server crash is thus prevented. Since the code is not behaving,
the READ operation returns -EIO to the client. None of the READ
payload data can be trusted if the splice actor isn't operating as
expected.

The get_expiry() function currently returns a timestamp, and uses the
special return value of 0 to indicate an error.
Unfortunately this causes a problem when 0 is the correct return value.
On a system with no RTC it is possible that the boot time will be seen
to be "3". When exportfs probes to see if a particular filesystem
supports NFS export it tries to cache information with an expiry time of
"3". The intention is for this to be "long in the past". Even with no
RTC it will not be far in the future (at most a second or two) so this
is harmless.
But if the boot time happens to have been calculated to be "3", then
get_expiry will fail incorrectly as it converts the number to "seconds
since bootime" - 0.
To avoid this problem we change get_expiry() to report the error quite
separately from the expiry time. The error is now the return value.
The expiry time is reported through a by-reference parameter.

After the wait for a grant is done (for whatever reason), nlmclnt_block
updates the status of the nlm_rqst with the status of the block. At the
point it does this, however, the block is still queued its status could
change at any time.
This is particularly a problem when the waiting task is signaled during
the wait. We can end up giving up on the lock just before the GRANTED_MSG
callback comes in, and accept it even though the lock request gets back
an error, leaving a dangling lock on the server.
Since the nlm_wait never lives beyond the end of nlmclnt_lock, put it on
the stack and add functions to allow us to enqueue and dequeue the
block. Enqueue it just before the lock/wait loop, and dequeue it
just after we exit the loop instead of waiting until the end of
the function. Also, scrape the status at the time that we dequeue it to
ensure that it's final.

On most filesystems, there is no reason to delay reaping an nfsd_file
just because its underlying inode is still under writeback. nfsd just
relies on client activity or the local flusher threads to do writeback.
The main exception is NFS, which flushes all of its dirty data on last
close. Add a new EXPORT_OP_FLUSH_ON_CLOSE flag to allow filesystems to
signal that they do this, and only skip closing files under writeback on
such filesystems.
Also, remove a redundant NULL file pointer check in
nfsd_file_check_writeback, and clean up nfs's export op flag
definitions.

The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in
the Renesas RZ/G2L family SoCs. It consists of eight 16-bit timer
channels and one 32-bit timer channel. It supports the following
functions
- Counter
- Timer
- PWM
The 8/16/32 bit registers are mixed in each channel.
Add MTU3a core driver for RZ/G2L SoC. The core driver shares the
clk and channel register access for the other child devices like
Counter, PWM and Clock event.

Implement a regulator driver with IRQ support for fault management.
Written against documentation [1] and [2] and tested on real hardware.
Every channel has it's own regulator supply nammed 'vss1-supply' and
'vss2-supply'. The regulator supply is used to determine the output
voltage, as the smart switch provides no output regulation.
The driver requires the 'shunt-resistor-micro-ohms' to be present in
the devicetree to properly calculate current related values.
You must specify compatible devictree layout:
regulator@3a {
reg = <0x3a>;
vss1-supply = <&p3v3>;
compatible = "maxim,max5978";
...
regulators {
sw0_ref: SW0 {
regulator-compatible = "SW0";
shunt-resistor-micro-ohms = <12000>;
...
}
}
}

Changes in V12:
- Use simple_mfd_i2c driver and remove previous implementation.
- Remove newline
- Use _MFD_MAX597X_H in header file
- Successfull build need following patch from regulator:
