Ziqi Chen 663d0c19f3 scsi: ufs: qcom: Check gear against max gear in vop freq_to_gear()
The vop freq_to_gear() may return a gear greater than the negotiated max
gear. Return the negotiated max gear if the mapped gear is greater.

Ziqi Chen e97633492f scsi: ufs: core: Don't perform UFS clkscaling during host async scan
When preparing for UFS clock scaling, the UFS driver will quiesce all
sdevs queues in the UFS SCSI host tagset list and then unquiesce them in
ufshcd_clock_scaling_unprepare(). If the UFS SCSI host async scan is in
progress at this time, some LUs may be added to the tagset list between
UFS clkscale prepare and unprepare. This can cause two issues:

1. During clock scaling, there may be I/O requests issued through new
added queues that have not been quiesced, leading to task abort issue.

2. These new added queues that have not been quiesced will be unquiesced
as well when UFS clkscale is unprepared, resulting in warning prints.

Therefore, use the mutex lock scan_mutex in
ufshcd_clock_scaling_prepare() and ufshcd_clock_scaling_unprepare() to
protect it.

After UFS_ABORT_TASK has been processed successfully, the host will
generate MCQ IRQ for ABORT TAG with response OCS_ABORTED. This results in
ufshcd_compl_one_cqe() calling ufshcd_release_scsi_cmd().

But ufshcd_mcq_abort() already calls ufshcd_release_scsi_cmd(), resulting
in __ufshcd_release() being called twice. This means
hba->clk_gating.active_reqs will be decreased twice, making it go
negative.

The default device command timeout remains 1.5 seconds, but platform
drivers can override it if needed.

Some UFS device commands may timeout due to being blocked by regular SCSI
write commands. Therefore, the maximum timeout needs to be extended to 30
seconds, matching the SCSI write command timeout. And for error injection
purposes, set the minimum value to 1 ms.

error case is tested in the 'if' that follows the allocation call, and
the default return value of the function is '0'.

The following patches made over Linus's tree remove the atomic use from
the main IO path. There was a handful of atomic_longs used just used
for stats and a couple atomics used for handling ordered commands. These
patches move the stats to per cpu, and moves the ordered tracking to a
per cpu counter.

With the patches 8K IOPS increases by up to 33% when running fio
with numjobs >= 4 and using the vhost-scsi target with virtio-scsi
and virtio num_queues >= 4 (jobs and queues match, and virtqueue_size
and cmd_per_lun are increased to match the total iodepth of all
jobs).

Mike Christie 268975a87c scsi: target: Move delayed/ordered tracking to per CPU
The atomic use from the delayed/ordered tracking is causing perf issues
when using higher perf backend devices and multiple queues.  This moves
the values to a per CPU counter. Combined with the per CPU stats patch,
this improves IOPS by up to 33% for 8K IOS when using 4 or more queues
from the initiator.

Martin K. Petersen a0d1cf505d Merge patch series "smartpqi updates"
Don Brace <don.brace@microchip.com> says:

These patches are based on Martin Petersen's 6.16/scsi-queue tree
  https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
  6.16/scsi-queue

There are two main functional changes in this patch series:
smartpqi-take-drives-offline-when-controller-is-offline
smartpqi-fix-smp_processor_id-call-trace-for-preemptible-kernels

The other two patches add PCI-IDs for new controllers and change the
driver version.

This set of changes consists of:

* smartpqi-take-drives-offline-when-controller-is-offline
     On rare occasions, the controller can lock up and the driver was
     removing the controller instance from OS but leaving the
     drives exposed and their state was still 'running'.

     This patch sets the drive state as 'offline' to avoid confusion.
* smartpqi-add-new-pci_ids
     Add support for more PCI devices.
* smartpqi-enhance_wwid-logging-logic
     Cosmetic change for logging WWIDs for NVMe devices and for drives
     that support the extended format.
* smartpqi-fix-smp_processor_id-call-trace-for-preemptible-kernels
     When preemption is enabled, there are call traces in the console
     logs which are annoying. The call trace mentions using
     smp_processor_id(). Since the driver is only using this function call
     when accessing a per_cpu variable, we changed the call to
     raw_smp_processor_id(). This patch was written by
     Yi Zhang <yi.zhang@redhat.com> and I am posting it on his behalf.
* smartpqi-update-driver-version-to-2.1.34-035
     No functional changes.

Yi Zhang 42d033cf4b scsi: smartpqi: Fix smp_processor_id() call trace for preemptible kernels
Correct kernel call trace when calling smp_processor_id() when called in
preemptible kernels by using raw_smp_processor_id().

smp_processor_id() checks to see if preemption is disabled and if not,
issue an error message followed by a call to dump_stack().
