change_num_qps() is still suspending/resuming VQs one by one.
This change switches to parallel suspend/resume.
When increasing the number of queues the flow has changed a bit for
simplicity: the setup_vq() function will always be called before
resume_vqs(). If the VQ is initialized, setup_vq() will exit early. If
the VQ is not initialized, setup_vq() will create it and resume_vqs()
will resume it.

change_num_qps() has a lot of multiplications by 2 to convert
the number of VQ pairs to number of VQs. This patch simplifies
the code by doing the VQP -> VQ count conversion at the beginning
in a variable.

Unregistering notifiers is a costly operation. Instead of removing
the notifiers during device suspend and adding them back at resume,
simply ignore the call when the device is suspended.
At resume time call queue_link_work() to make sure that the device state
is propagated in case there were changes.
For 1 vDPA device x 32 VQs (16 VQPs) attached to a large VM (256 GB RAM,
32 CPUs x 2 threads per core), the device suspend time is reduced from
~13 ms to ~2.5 ms.

Currently device resume works on vqs serially. Building up on previous
changes that converted vq operations to the async api, this patch
parallelizes the device resume.

Currently device suspend works on vqs serially. Building up on previous
changes that converted vq operations to the async api, this patch
parallelizes the device suspend:
1) Suspend all active vqs parallel.
2) Query suspended vqs in parallel.
For 1 vDPA device x 32 VQs (16 VQPs) attached to a large VM (256 GB RAM,
32 CPUs x 2 threads per core), the device suspend time is reduced from
~37 ms to ~13 ms.
A later patch will remove the link unregister operation which will make
it even faster.

Switch firmware vq modify command to be issued via the async API to
allow future parallelization. The new refactored function applies the
modify on a range of vqs and waits for their execution to complete.
For now the command is still used in a serial fashion. A later patch

Introduce a new function mlx5_vdpa_exec_async_cmds() which
wraps the mlx5_core async firmware command API in a way
that will be used to parallelize certain operation in this

The wrapper deals with the case when mlx5_cmd_exec_cb() returns

Currently, commands that qualify as throttled can't be used via the
async API. That's due to the fact that the throttle semaphore can sleep
but the async API can't.
This patch allows throttling in the async API by using the tentative
variant of the semaphore and upon failure (semaphore at 0) returns EBUSY
to signal to the caller that they need to wait for the completion of
previously issued commands.
Furthermore, make sure that the semaphore is released in the callback.

On PVH dom0, when passthrough a device to domU, QEMU and xl tools
want to use gsi number to do pirq mapping, see QEMU code
xen_pt_realize->xc_physdev_map_pirq, and xl code
pci_add_dm_done->xc_physdev_map_pirq, but in current codes, the gsi
number is got from file /sys/bus/pci/devices/<sbdf>/irq, that is
wrong, because irq is not equal with gsi, they are in different
spaces, so pirq mapping fails.
And in current linux codes, there is no method to get gsi
for userspace.
For above purpose, record gsi of pcistub devices when init
pcistub and add a new syscall into privcmd to let userspace
can get gsi when they have a need.

When device on dom0 side has been reset, the vpci on Xen side
won't get notification, so that the cached state in vpci is
all out of date with the real device state.
To solve that problem, add a new function to clear all vpci
device state when device is reset on dom0 side.
And call that function in pcistub_init_device. Because when
using "pci-assignable-add" to assign a passthrough device in
Xen, it will reset passthrough device and the vpci state will
out of date, and then device will fail to restore bar state.

Any non-posted read should flush the previous write, so we don't
necessarily need to read back the value we just wrote. I've found at
least some controllers that respond with 0 for short moments after
writing the CC register with EN (enable) cleared, so the read-back is
overwriting our valid ctrl_config value and ends up breaking on the
subsequent enabling.

During repetitive namespace remapping operations on the target the

This happens when we have several paths, some of which are inaccessible,
and the active paths are removed first. Then nvme_find_path() will requeue
I/O in the ns_head (as paths are present), but the requeue list is never
triggered as all remaining paths are inactive.
This patch checks for NVME_NSHEAD_DISK_LIVE in nvme_available_path(),
and requeue I/O after NVME_NSHEAD_DISK_LIVE has been cleared once
the last path has been removed to properly terminate pending I/O.

The cifs flag CIFS_INO_MODIFIED_ATTR, which indicates that the mtime and
ctime need to be written back on close, got taken over by netfs as
NETFS_ICTX_MODIFIED_ATTR to avoid the need to call a function pointer to
set it.
The flag gets set correctly on buffered writes, but doesn't get set by
netfs_page_mkwrite(), leading to occasional failures in generic/080 and
generic/215.
Fix this by setting the flag in netfs_page_mkwrite().

cifs_read_iter_from_socket() copies the iterator that's passed in for the
socket to modify as and if it will, and then advances the original iterator
by the amount sent. However, both callers revert the advancement (although
receive_encrypted_read() zeros beyond the iterator first). The problem is,
though, that cifs_readv_receive() reverts by the original length, not the
amount transmitted which can cause an oops in iov_iter_revert().
Fix this by:
(1) Remove the iov_iter_advance() from cifs_read_iter_from_socket().
(2) Remove the iov_iter_revert() from both callers. This fixes the bug in
cifs_readv_receive().
(3) In receive_encrypted_read(), if we didn't get back as much data as the
buffer will hold, copy the iterator, advance the copy and use the copy
to drive iov_iter_zero().
As a bonus, this gets rid of some unnecessary work.
This was triggered by generic/074 with the "-o sign" mount option.

below:

root:~# stat -c %a /mnt2/readonly-file

Pull exfat updates from Namjae Jeon:
- Clean-up unnecessary codes as ->valid_size is supported
- buffered-IO fallback is no longer needed when using direct-IO
- Move ->valid_size extension from mmap to ->page_mkwrite. This
improves the overhead caused by unnecessary zero-out during mmap.

Pull f2fs updates from Jaegeuk Kim:
"The main changes include converting major IO paths to use folio, and
adding various knobs to control GC more flexibly for Zoned devices.
In addition, there are several patches to address corner cases of
atomic file operations and better support for file pinning on zoned
device.
Enhancement:
- add knobs to tune foreground/background GCs for Zoned devices
- convert IO paths to use folio
- reduce expensive checkpoint trigger frequency
- allow F2FS_IPU_NOCACHE for pinned file
- forcibly migrate to secure space for zoned device file pinning
- get rid of buffer_head use
- add write priority option based on zone UFS
- get rid of online repair on corrupted directory
Bug fixes:
- fix to don't panic system for no free segment fault injection
- fix to don't set SB_RDONLY in f2fs_handle_critical_error()
- avoid unused block when dio write in LFS mode
- compress: don't redirty sparse cluster during {,de}compress
- check discard support for conventional zones
- atomic: prevent atomic file from being dirtied before commit
- atomic: fix to check atomic_file in f2fs ioctl interfaces
- atomic: fix to forbid dio in atomic_file
- atomic: fix to truncate pagecache before on-disk metadata truncation
- atomic: create COW inode from parent dentry
- atomic: fix to avoid racing w/ GC
- atomic: require FMODE_WRITE for atomic write ioctls
- fix to wait page writeback before setting gcing flag
- fix to avoid racing in between read and OPU dio write, dio completion
- fix several potential integer overflows in file offsets and dir_block_index
- fix to avoid use-after-free in f2fs_stop_gc_thread()
As usual, there are several code clean-ups and refactorings"

When doing the direct-io reads it will also try to mark pages dirty,
but for the read path it won't hold the Fw caps and there is case
will it get the Fw reference.

The cap_auths that are allocated during an MDS session opening are never
released, causing a memory leak detected by kmemleak. Fix this by freeing
the memory allocated when shutting down the MDS client.

We have hit a race between cap releases and cap revoke request
that will cause the check_caps() to miss sending a cap revoke ack
to MDS. And the client will depend on the cap release to release
that revoking caps, which could be delayed for some unknown reasons.
In Kclient we have figured out the RCA about race and we need
a way to explictly trigger this manually could help to get rid
of the caps revoke stuck issue.
