This patch fixes a race in async lock request handling between adding
the relevant struct nlm_block to nlm_blocked list after the request was
sent by vfs_lock_file() and nlmsvc_grant_deferred() does a lookup of the
nlm_block in the nlm_blocked list. It could be that the async request is
completed before the nlm_block was added to the list. This would end
in a -ENOENT and a kernel log message of "lockd: grant for unknown
block".
To solve this issue we add the nlm_block before the vfs_lock_file() call
to be sure it has been added when a possible nlmsvc_grant_deferred() is
called. If the vfs_lock_file() results in an case when it wouldn't be
added to nlm_blocked list, the nlm_block struct will be removed from
this list again.

This patch returns nlm_lck_blocked in nlmsvc_lock() when an asynchronous
lock request is pending. During testing I ran into the case with the
side-effects that lockd is waiting for only one lm_grant() callback
because it's already part of the nlm_blocked list. If another
asynchronous for the same nlm_block is triggered two lm_grant()
callbacks will occur but lockd was only waiting for one.
To avoid any change of existing users this handling will only being made
when export_op_support_safe_async_lock() returns true.

This patch reverts mostly commit 40595cdc93 ("nfs: block notification
on fs with its own ->lock") and introduces an EXPORT_OP_ASYNC_LOCK
export flag to signal that the "own ->lock" implementation supports
async lock requests. The only main user is DLM that is used by GFS2 and
OCFS2 filesystem. Those implement their own lock() implementation and
return FILE_LOCK_DEFERRED as return value. Since commit 40595cdc93
("nfs: block notification on fs with its own ->lock") the DLM
implementation were never updated. This patch should prepare for DLM
to set the EXPORT_OP_ASYNC_LOCK export flag and update the DLM
plock implementation regarding to it.

If fsync() is returning EAGAIN, then we can assume that the filesystem
being exported is something like NFS with the 'softerr' mount option
enabled, and that it is just asking us to replay the fsync() operation
at a later date.
If we see an ESTALE, then ditto: the file is gone, so there is no danger
of losing the error.
For those cases, do not reset the write verifier. A write verifier
change has a global effect, causing retransmission by all clients of
all uncommitted unstable writes for all files, so it is worth
mitigating where possible.

The nfsd_open code handles EOPENSTALE correctly, by retrying the call to
fh_verify() and __nfsd_open(). However the filecache just drops the
error on the floor, and immediately returns nfserr_stale to the caller.
This patch ensures that we propagate the EOPENSTALE code back to
nfsd_file_do_acquire, and that we handle it correctly.

b1472a60a5 ("x86/smp: Don't send INIT to boot CPU")
because it seems to result in hung machines at shutdown. Particularly
some Dell machines, but Thomas says
"The rest seems to be Lenovo and Sony with Alderlake/Raptorlake CPUs -
at least that's what I could figure out from the various bug reports.
I don't know which CPUs the DELL machines have, so I can't say it's a
pattern.
I agree with the revert for now"
Ashok Raj chimes in:
"There was a report (probably this same one), and it turns out it was a
bug in the BIOS SMI handler.
The client BIOS's were waiting for the lowest APICID to be the SMI
rendevous master. If this is MeteorLake, the BSP wasn't the one with
the lowest APIC and it triped here.
The BIOS change is also being pushed to others for assimilation :)
Server BIOS's had this correctly for a while now"
and it does look likely to be some bad interaction between SMI and the
non-BSP cores having put into INIT (and thus unresponsive until reset).

Kernel v6.5 converted overlayfs to new mount api.
As an added bonus, it also added a feature to allow appending lowerdirs
using lowerdir=:/lower2,lowerdir=::/data3 syntax.
This new syntax has raised some concerns regarding escaping of colons.
We decided to try and disable this syntax, which hasn't been in the wild
for so long and introduce it again in 6.7 using explicit mount options
lowerdir+=/lower2,datadir+=/data3.

Before commit b36a5780cb ("ovl: modify layer parameter parsing"),
spaces and commas in lowerdir mount option value used to be escaped using
seq_show_option().
In current upstream, when lowerdir value has a space, it is not escaped
in /proc/mounts, e.g.:
none /mnt overlay rw,relatime,lowerdir=l l,upperdir=u,workdir=w 0 0
which results in broken output of the mount utility:
none on /mnt type overlay (rw,relatime,lowerdir=l)
Store the original lowerdir mount options before unescaping and show
them using the same escaping used for seq_show_option() in addition to
escaping the colon separator character.

has the wait in the RMI4 code)

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.
SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.
Note that originally the delay was added to psmouse driver in
92e24e0e57 ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

When the SMBus connection is attempted psmouse_smbus_init() sets
the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus
initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will
fallback to PS/2 mode, replacing the psmouse private data. This can cause
issues on resume, since psmouse_smbus_reconnect() expects to find an
instance of struct psmouse_smbus_dev in psmouse->private.
The issue was uncovered when in 92e24e0e57 ("Input: psmouse - add
delay when deactivating for SMBus mode") psmouse_smbus_reconnect()
started attempting to use more of the data structure. The commit was
since reverted, not because it was at fault, but because there was found
a better way of doing what it was attempting to do.
Fix the problem by resetting the fast_reconnect pointer in psmouse
structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2
mode is used.

Because fp is never NULL when rc is zero. This patch add null check for fp
in ksmbd_update_fstate to make alarm silence.

set_smb2_rsp_status() after __process_request() sets the wrong error
status. This patch resets all iov vectors and sets the error status
on clean one.

Fixes for v6.6-rc5
- fix to not reset the PHY everytime we start link training but only
do it if link training fails. Without this, the PLL unlocked
interrupt fires causing "Unexpected DP AUX IRQ 0x01000000 when
not busy" spam in the logs since last 2-3 cycles
- correct the highest bank bit to match downstream device tree for
msm8998
- skip the video mode wait if the timing engine is not enabled. This
was introduced after pre_enable flag for DSI video mode panels
where we would end up waiting for the video mode done interrupt
even before enabling timing engine causing error spam and long
bootup times.
- check the correct return code of irq_of_parse_and_map() in DSI code
- avoid overflow issues in the dpu bandwidth calculation . This was
exposed for high resolution displays and a critical fix to avoid
atomic_check failure
- minor fix to add new lines in DP print messages.
- Fix to fail atomic_check() if the resolution exceeds max mdp clk.
This leads to underflow otherwise if we try to allow that frame.

This reverts commit 92e24e0e57.
While the patch itself is correct, it uncovered an issue with fallback
to PS/2 mode, where we were leaving psmouse->fast_reconnect handler set
to psmouse_smbus_reconnect(), which caused crashes.
While discussing various approaches to fix the issue it was noted that
this patch ass undesired delay in the "fast" resume path of PS/2 device,
and it would be better to actually use "reset_delay" option defined in
struct rmi_device_platform_data and have RMI code handle it for SMBus
transport as well. So this patch is being reverted to deal with crashes
and a better solution will be merged shortly.
