Pull vfs inode time accessor updates from Christian Brauner:
"This finishes the conversion of all inode time fields to accessor
functions as discussed on list. Changing timestamps manually as we
used to do before is error prone. Using accessors function makes this
robust.
It does not contain the switch of the time fields to discrete 64 bit
integers to replace struct timespec and free up space in struct inode.
But after this, the switch can be trivially made and the patch should
only affect the vfs if we decide to do it"

Pull vfs xattr updates from Christian Brauner:
"The 's_xattr' field of 'struct super_block' currently requires a
mutable table of 'struct xattr_handler' entries (although each handler
itself is const). However, no code in vfs actually modifies the
tables.
This changes the type of 's_xattr' to allow const tables, and modifies
existing file systems to move their tables to .rodata. This is
desirable because these tables contain entries with function pointers
in them; moving them to .rodata makes it considerably less likely to
be modified accidentally or maliciously at runtime"

Pull iov_iter updates from Christian Brauner:
"This contain's David's iov_iter cleanup work to convert the iov_iter
iteration macros to inline functions:
- Remove last_offset from iov_iter as it was only used by ITER_PIPE
- Add a __user tag on copy_mc_to_user()'s dst argument on x86 to
match that on powerpc and get rid of a sparse warning
- Convert iter->user_backed to user_backed_iter() in the sound PCM
driver
- Convert iter->user_backed to user_backed_iter() in a couple of
infiniband drivers
- Renumber the type enum so that the ITER_* constants match the order
in iterate_and_advance*()
- Since the preceding patch puts UBUF and IOVEC at 0 and 1, change
user_backed_iter() to just use the type value and get rid of the
extra flag
- Convert the iov_iter iteration macros to always-inline functions to
make the code easier to follow. It uses function pointers, but they
get optimised away
- Move the check for ->copy_mc to _copy_from_iter() and
copy_page_from_iter_atomic() rather than in memcpy_from_iter_mc()
where it gets repeated for every segment. Instead, we check once
and invoke a side function that can use iterate_bvec() rather than
iterate_and_advance() and supply a different step function
- Move the copy-and-csum code to net/ where it can be in proximity
with the code that uses it
- Fold memcpy_and_csum() in to its two users
- Move csum_and_copy_from_iter_full() out of line and merge in
csum_and_copy_from_iter() since the former is the only caller of
the latter

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Rename and export helpers that get write access to a mount. They
are used in overlayfs to get write access to the upper mount.
- Print the pretty name of the root device on boot failure. This
helps in scenarios where we would usually only print
"unknown-block(1,2)".
- Add an internal SB_I_NOUMASK flag. This is another part in the
endless POSIX ACL saga in a way.
When POSIX ACLs are enabled via SB_POSIXACL the vfs cannot strip
the umask because if the relevant inode has POSIX ACLs set it might
take the umask from there. But if the inode doesn't have any POSIX
ACLs set then we apply the umask in the filesytem itself. So we end
up with:
(1) no SB_POSIXACL -> strip umask in vfs
(2) SB_POSIXACL -> strip umask in filesystem
The umask semantics associated with SB_POSIXACL allowed filesystems
that don't even support POSIX ACLs at all to raise SB_POSIXACL
purely to avoid umask stripping. That specifically means NFS v4 and
Overlayfs. NFS v4 does it because it delegates this to the server
and Overlayfs because it needs to delegate umask stripping to the
upper filesystem, i.e., the filesystem used as the writable layer.
This went so far that SB_POSIXACL is raised eve on kernels that
don't even have POSIX ACL support at all.
Stop this blatant abuse and add SB_I_NOUMASK which is an internal
superblock flag that filesystems can raise to opt out of umask
handling. That should really only be the two mentioned above. It's
not that we want any filesystems to do this. Ideally we have all
umask handling always in the vfs.
- Make overlayfs use SB_I_NOUMASK too.
- Now that we have SB_I_NOUMASK, stop checking for SB_POSIXACL in
IS_POSIXACL() if the kernel doesn't have support for it. This is a
very old patch but it's only possible to do this now with the wider
cleanup that was done.
- Follow-up work on fake path handling from last cycle. Citing mostly
from Amir:
When overlayfs was first merged, overlayfs files of regular files
and directories, the ones that are installed in file table, had a
"fake" path, namely, f_path is the overlayfs path and f_inode is
the "real" inode on the underlying filesystem.
In v6.5, we took another small step by introducing of the
backing_file container and the file_real_path() helper. This change
allowed vfs and filesystem code to get the "real" path of an
overlayfs backing file. With this change, we were able to make
fsnotify work correctly and report events on the "real" filesystem
objects that were accessed via overlayfs.
This method works fine, but it still leaves the vfs vulnerable to
new code that is not aware of files with fake path. A recent
example is commit db1d1e8b9867 ("IMA: use vfs_getattr_nosec to get
the i_version"). This commit uses direct referencing to f_path in
IMA code that otherwise uses file_inode() and file_dentry() to
reference the filesystem objects that it is measuring.
This contains work to switch things around: instead of having
filesystem code opt-in to get the "real" path, have generic code
opt-in for the "fake" path in the few places that it is needed.
Is it far more likely that new filesystems code that does not use
the file_dentry() and file_real_path() helpers will end up causing
crashes or averting LSM/audit rules if we keep the "fake" path
exposed by default.
This change already makes file_dentry() moot, but for now we did
not change this helper just added a WARN_ON() in ovl_d_real() to
catch if we have made any wrong assumptions.
After the dust settles on this change, we can make file_dentry() a
plain accessor and we can drop the inode argument to ->d_real().
- Switch struct file to SLAB_TYPESAFE_BY_RCU. This looks like a small
change but it really isn't and I would like to see everyone on
their tippie toes for any possible bugs from this work.
Essentially we've been doing most of what SLAB_TYPESAFE_BY_RCU for
files since a very long time because of the nasty interactions
between the SCM_RIGHTS file descriptor garbage collection. So
extending it makes a lot of sense but it is a subtle change. There
are almost no places that fiddle with file rcu semantics directly
and the ones that did mess around with struct file internal under
rcu have been made to stop doing that because it really was always
dodgy.
I forgot to put in the link tag for this change and the discussion
in the commit so adding it into the merge message:

Cleanups:
- Various smaller pipe cleanups including the removal of a spin lock
that was only used to protect against writes without pipe_lock()
from O_NOTIFICATION_PIPE aka watch queues. As that was never
implemented remove the additional locking from pipe_write().
- Annotate struct watch_filter with the new __counted_by attribute.
- Clarify do_unlinkat() cleanup so that it doesn't look like an extra
iput() is done that would cause issues.
- Simplify file cleanup when the file has never been opened.
- Use module helper instead of open-coding it.
- Predict error unlikely for stale retry.
- Use WRITE_ONCE() for mount expiry field instead of just commenting
that one hopes the compiler doesn't get smart.
Fixes:
- Fix readahead on block devices.
- Fix writeback when layztime is enabled and inodes whose timestamp
is the only thing that changed reside on wb->b_dirty_time. This
caused excessively large zombie memory cgroup when lazytime was
enabled as such inodes weren't handled fast enough.
- Convert BUG_ON() to WARN_ON_ONCE() in open_last_lookups()"

Pull vfs superblock updates from Christian Brauner:
"This contains the work to make block device opening functions return a
struct bdev_handle instead of just a struct block_device. The same
struct bdev_handle is then also passed to block device closing
functions.
This allows us to propagate context from opening to closing a block
device without having to modify all users everytime.
Sidenote, in the future we might even want to try and have block
device opening functions return a struct file directly but that's a
series on top of this.
These are further preparatory changes to be able to count writable
opens and blocking writes to mounted block devices. That's a separate
piece of work for next cycle and for that we absolutely need the
changes to btrfs that have been quietly dropped somehow.
Originally the series contained a patch that removed the old
blkdev_*() helpers. But since this would've caused needles churn in
-next for bcachefs we ended up delaying it.
The second piece of work addresses one of the major annoyances about
the work last cycle, namely that we required dropping s_umount
whenever we used the superblock and fs_holder_ops for a block device.
The reason for that requirement had been that in some codepaths
s_umount could've been taken under disk->open_mutex (that's always
been the case, at least theoretically). For example, on surprise block
device removal or media change. And opening and closing block devices
required grabbing disk->open_mutex as well.
So we did the work and went through the block layer and fixed all
those places so that s_umount is never taken under disk->open_mutex.
This means no more brittle games where we yield and reacquire s_umount
during block device opening and closing and no more requirements where
block devices need to be closed. Filesystems don't need to care about
this.
There's a bunch of other follow-up work such as moving block device
freezing and thawing to holder operations which makes it work for all
block devices and not just the main block device just as we did for
surprise removal. But that is for next cycle.

Swarup reported a "make htmldocs" warning:
Variable length lookbehind is experimental in regex;
marked by <-- HERE in m/(?<=^|\s)-Werror(?=$|\s)
<-- HERE / at ./scripts/kernel-doc line 188.
Akira managed to reproduce it by perl v5.34.0.
On second thought, it is not necessary to have the complicated
"lookahead and lookbehind" things, and the regex can be simplified.
Generally, the kernel-doc warnings should be considered as errors only
when "-Werror" flag is set in KCFLAGS, but not when
"-Werror=<diagnostic-type>" is set, which means there needs to be a
space or start of string before "-Werror", and a space or end of string
after "-Werror".
The following cases have been tested to work as expected:
* kernel-doc warnings are considered as errors:
$ KCFLAGS="-Werror" make W=1
$ KCFLAGS="-Wcomment -Werror" make W=1
$ KCFLAGS="-Werror -Wundef" make W=1
$ KCFLAGS="-Wcomment -Werror -Wundef" make W=1
* kernel-doc warnings remain as warnings:
$ KCFLAGS="-Werror=return-type" make W=1
$ KCFLAGS="-Wcomment -Werror=return-type" make W=1
$ KCFLAGS="-Werror=return-type -Wundef" make W=1
$ KCFLAGS="-Wcomment -Werror=return-type -Wundef" make W=1
The "Variable length lookbehind is experimental in regex" warning is
also resolved by this patch.

iommufd_test_dirty()/IOMMU_TEST_OP_DIRTY sets the dirty bits in the mock
domain implementation that the userspace side validates against what it
obtains via the UAPI.
However in introducing iommufd_test_dirty() it forgot to validate page_size
being 0 leading to two possible divide-by-zero problems: one at the
beginning when calculating @max and while calculating the IOVA in the
XArray PFN tracking list.
While at it, validate the length to require non-zero value as well, as we
can't be allocating a 0-sized bitmap.

An excerpt from the PA8800 ERS states:
* The PA8800 violates the seven instruction pipeline rule when performing
TLB inserts or PxTLBE instructions with the PSW C bit on. The instruction
will take effect by the 12th instruction after the insert or purge.
I believe we have a problem with handling TLB misses. We don't fill
the pipeline following TLB inserts. As a result, we likely fault again
after returning from the interruption.
The above statement indicates that we need at least seven instructions
after the insert on pre PA8800 processors and we need 12 instructions
on PA8800/PA8900 processors.
Here we add macros and code to provide the required number instructions
after a TLB insert.

smp_prepare_boot_cpu() reads the cpuid of the first CPU, printing a
message to state which processor booted, and setting it online and
present.
This cpuid is retrieved from per_cpu(cpu_data, 0).cpuid, which is
initialised in arch/parisc/kernel/processor.c:processor_probe() thusly:
p = &per_cpu(cpu_data, cpuid);
...
p->cpuid = cpuid; /* save CPU id */
Consequently, the cpuid retrieved seems to be guaranteed to also be
zero, meaning that the message printed in this boils down to:
pr_info("SMP: bootstrap CPU ID is 0\n");
Moreover, since kernel/cpu.c::boot_cpu_init() already sets CPU 0 to
be present and online, there is no need to do this again in
smp_prepare_boot_cpu().
Remove this code, and simplify the printk().

This reverts commit 7bebd832177670e6cce1783cf144f989cd3cf4b5.
The patch series that removed typedefs from the octeon driver was not
actually built properly, and broke the build (it's hard to test-build
this driver for some reason.) Remove them all at this point in time to
make sure the build works properly.

MPS Flow
Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer High Flow USB flow sensor, which communicates through a
proprietary USB HID protocol. This commit also adds support for the sensors
of the MPS Flow devices, as they have the same USB product ID and sensor
layouts. Implemented by Leonard Anderweit [1].
Internal and external temp sensor readings are available, along with
the flow sensor.
Additionally, serial number and firmware version are exposed through
debugfs.

Add support for LTC2991 Octal I2C Voltage, Current, and Temperature
Monitor.
The LTC2991 is used to monitor system temperatures, voltages and
currents. Through the I2C serial interface, the eight monitors can
individually measure supply voltages and can be paired for
differential measurements of current sense resistors or temperature
sensing transistors. Additional measurements include internal
temperature and internal VCC.

The newly introduced function is global but only called in this one
file and has no extern prototype, so it should probably be static:

Solve two ergonomic issues with struct seq_buf;
1) Too much boilerplate is required to initialize:
struct seq_buf s;
char buf[32];
seq_buf_init(s, buf, sizeof(buf));
Instead, we can build this directly on the stack. Provide
DECLARE_SEQ_BUF() macro to do this:
DECLARE_SEQ_BUF(s, 32);
2) %NUL termination is fragile and requires 2 steps to get a valid
C String (and is a layering violation exposing the "internals" of
seq_buf):
seq_buf_terminate(s);
do_something(s->buffer);
Instead, we can just return s->buffer directly after terminating it in
the refactored seq_buf_terminate(), now known as seq_buf_str():
do_something(seq_buf_str(s));
