If we (re-)calculate the file system overhead amount and it's
different from the on-disk s_overhead_clusters value, update the
on-disk version since this can take potentially quite a while on
bigalloc file systems.

We need to either restore creds properly if we fail on the file
assignment, or just do the file assignment first instead. Let's do
the latter as it's simpler, should make no difference here for
file assignment.

If the file system does not use bigalloc, calculating the overhead is
cheap, so force the recalculation of the overhead so we don't have to
trust the precalculated overhead in the superblock.

Currently ksmbd is using ->f_bsize from vfs_statfs() as sector size.
If fat/exfat is a local share, ->f_bsize is a cluster size that is too
large to be used as a sector size. Sector sizes larger than 4K cause
problem occurs when mounting an iso file through windows client.
The error message can be obtained using Mount-DiskImage command,
the error is:
"Mount-DiskImage : The sector size of the physical disk on which the
virtual disk resides is not supported."
This patch reports fixed 4KB sector size if ->s_blocksize is bigger
than 4KB.

The intent behind commit e6fc9f62ce6e ("dm: flag clones created by
__send_duplicate_bios") was to formally disallow the use of
dm_accept_partial_bio() where it simply isn't possible -- due to
constraint that multiple bios cannot meaningfully update a shared
tio->len_ptr.
But that commit went too far and disallowed the case where "abormal"
IO (e.g. WRITE_ZEROES) is only using a single bio. Fix this by
not marking a dm_io with a single dm_target_io (and bio), that happens
to be created by __send_duplicate_bios, as DM_TIO_IS_DUPLICATE_BIO.
Also remove 'unsigned *len' parameter from alloc_multiple_bios().
This commit fixes a dm_accept_partial_bio() BUG_ON() with dm-zoned
when a WRITE_ZEROES bio is issued.

The latest GuC firmware drops the context descriptor pool in favour of
passing all creation data in the create H2G. It also greatly simplifies
the work queue and removes the process descriptor used for multi-LRC
submission. So, remove all mention of LRC and process descriptors and
update the registration code accordingly.
Unfortunately, the new API also removes the ability to set default
values for the scheduling policies at context registration time.
Instead, a follow up H2G must be sent. The individual scheduling
policy update H2G commands are also dropped in favour of a single KLV
based H2G. So, change the update wrappers accordingly and call this
during context registration..
Of course, this second H2G per registration might fail due to being
backed up. The registration code has a complicated state machine to
cope with the actual registration call failing. However, if that works
then there is no support for unwinding if a further call should fail.
Unwinding would require sending a H2G to de-register - but that can't
be done because the CTB is already backed up.
So instead, add a new flag to say whether the context has a pending
policy update. This is set if the policy H2G fails at registration
time. The submission code checks for this flag and retries the policy
update if set. If that call fails, the submission path early exists
with a retry error. This is something that is already supported for
other reasons.

When asked to create a path ending '/', but which is not to be a
directory (LOOKUP_DIRECTORY not set), filename_create() will never try
to create the file. If it doesn't exist, -ENOENT is reported.
However, it still passes LOOKUP_CREATE|LOOKUP_EXCL to the filesystems
->lookup() function, even though there is no intent to create. This is
misleading and can cause incorrect behaviour.
If you try
ln -s foo /path/dir/
where 'dir' is a directory on an NFS filesystem which is not currently
known in the dcache, this will fail with ENOENT.
But as the name is not in the dcache, nfs_lookup gets called with
LOOKUP_CREATE|LOOKUP_EXCL and so it returns NULL without performing any
lookup, with the expectation that a subsequent call to create the target
will be made, and the lookup can be combined with the creation. In the
case with a trailing '/' and no LOOKUP_DIRECTORY, that call is never
made. Instead filename_create() sees that the dentry is not (yet)
positive and returns -ENOENT - even though the directory actually
exists.
So only set LOOKUP_CREATE|LOOKUP_EXCL if there really is an intent to
create, and use the absence of these flags to decide if -ENOENT should
be returned.
Note that filename_parentat() is only interested in LOOKUP_REVAL, so we
split that out and store it in 'reval_flag'. __lookup_hash() then gets
reval_flag combined with whatever create flags were determined to be
needed.

The Gemini defconfig needs to be updated due to DSA driver
Kconfig changes in the v5.18 merge window:
CONFIG_NET_DSA_REALTEK_SMI is now behind
CONFIG_NET_DSA_REALTEK and the desired DSA switch need
to be selected explicitly with
CONFIG_NET_DSA_REALTEK_RTL8366RB.
Take this opportunity to update some other minor config
options:
- CONFIG_MARVELL_PHY moved around because of Kconfig
changes.
- CONFIG_SENSORS_DRIVETEMP should be selected since is
regulates the system critical alert temperature on
some devices, which is nice if it is handled even
if initramfs or root fails to mount.

[why]
These static variables save the RLC Scratch registers address.
When we install multiple GPUs (for example: XGMI setting) and
multiple GPUs call the function at same time. The RLC Scratch
registers address are changed each other. Then it caused
reading/writing from/to wrong GPU.
[how]
Removed the static from the variables. The variables are
on the stack.

This reverts commit 863fa85e6a01c8b239009825dd9de1f64d7d020a.
While we were testing DCN3.1 with a hub, we noticed that only one of 2
connected displays lights up when using some specific display
resolution. In summary, this was the setup:
1. Displays:
* Sharp LQ156M1JW26 (eDP): 1080@240
* BENQ SW320 (DP): 4k@60
* BENQ EX3203R (DP): 4k@60
2. Hub: Club3D CSV-7300

introduced this issue. We are investigating why this patch introduced
this regression, but we need to revert it for now.

Factor out from drm_dp_dpcd_read() a function to probe a DPCD address
with a 1-byte read access. This will be needed by the next patch doing a
read from an LTTPR address, which must happen without the preceding
wake-up read in drm_dp_dpcd_read().
While at it add tracing for the 1 byte read even if the read was
successful.

"A few more code and warning fixes.
There's one feature ioctl removal patch slated for 5.18 that did not
make it to the main pull request. It's just a one-liner and the ioctl
has a v2 that's in use for a long time, no point to postpone it to
5.19.
Late update:
- remove balance v1 ioctl, superseded by v2 in 2012
Fixes:
- add back cgroup attribution for compressed writes
- add super block write start/end annotations to asynchronous balance
- fix root reference count on an error handling path
- in zoned mode, activate zone at the chunk allocation time to avoid
ENOSPC due to timing issues

Below steps end up with crash:
- modprobe ice
- devlink dev eswitch set $PF1_PCI mode switchdev
- echo 64 > /sys/class/net/$PF1/device/sriov_numvfs
- rmmod ice
Calling ice_eswitch_port_start_xmit while the process of removing
VFs is in progress ends up with NULL pointer dereference.
That's because PR netdev is not released but some resources
are already freed. Fix it by checking if ICE_VF_DIS bit is set.

Currently for !CONFIG_NET_SWITCHDEV kernel builds it is not possible to
create VFs properly as call to ice_eswitch_configure() returns
-EOPNOTSUPP for us. This is because CONFIG_ICE_SWITCHDEV depends on
CONFIG_NET_SWITCHDEV.
Change the ice_eswitch_configure() implementation for
!CONFIG_ICE_SWITCHDEV to return 0 instead -EOPNOTSUPP and let
ice_ena_vfs() finish its work properly.

__ice_alloc_rx_bufs_zc() checks if a number of the descriptors to be
allocated would cause the ring wrap. In that case, driver will issue two
calls to xsk_buff_alloc_batch() - one that will fill the ring up to the
end and the second one that will start with filling descriptors from the
beginning of the ring.
ice_fill_rx_descs() is a wrapper for taking care of what
xsk_buff_alloc_batch() gave back to the driver. It works in a best
effort approach, so for example when driver asks for 64 buffers,
ice_fill_rx_descs() could assign only 32. Such case needs to be checked
when ring is being filled up to the end, because in that situation ntu
might not reached the end of the ring.
Fix the ring wrap by checking if nb_buffs_extra has the expected value.
If not, bump ntu and go directly to tail update.
