The ufshcd_scsi_block_requests() and ufshcd_scsi_unblock_requests()
calls were introduced in ufshcd_exception_event_handler() to prevent
that querying the exception event information would time out. Commit
10fe5888a4 ("scsi: ufs: increase the scsi query response timeout")
increased the timeout for querying exception information from 30 ms to
1.5 s and thereby eliminated the risk that a timeout would happen.
Hence, the calls to block and unblock SCSI requests are superfluous.
Remove these calls.

information can be viewed in the directory with the maximum number in
the dump directory.
After this series patch, the driver creates all debugfs directories and
files during initialization. Therefore, users cannot know the directory
where the latest dump information is stored. So, add latest_dump file to
notify users where the latest dump information is stored.

The SATA disk will be locked after the disk sends the DMA Setup frame
until all data frame transmission is completed. The
CFG_ICT_TIMER_STEP_TRSH register is used for sata disk to configure the
step size of the timer which records the time when the disk is
locked. The unit is 1us and the default step size is 150ms. If the disk
is locked for more than 7 timer steps, the io to be sent to the disk
will end abnormally.
The current timeout is only about 1 second, it is easy to trigger IO
abnormal end when the SATA hard disk returns data slowly. Adjust the
timeout to 7 seconds based on ERC time of most disks.

[ 4682.868084][ C129] Disabling IRQ #134
When the IRQ management layer processes each hardware interrupt, if the
return value of the interrupt handler is IRQ_WAKE_THREAD, it will wake
up the handler thread for this interrupt action and set IRQTF_RUNTHREAD
flag, wait for the interrupt handling thread to clear the
IRQTF_RUNTHREAD flag after execution. Later in note_interrupt(), use
irq_count to count hardware interrupts and irqs_unhandled to count
interrupts for which no thread handler is responsible. When irq_count
reaches 100000 and irqs_unhandled reaches 99000, irq will be disabled.
In the performance test scenario, I/O completion hardware interrupts are
continuously and quickly generated. As a result, the interrupt
processing thread is cyclically called in irq_thread() and does not
exit, this affects the response of the interrupt thread to the hardware
interrupt and causes irqs_unhandled to grow to 99000. Finally, the irq
is disabled.
Therefore, default enable interrupt coalescing to reduce the generation
of hardware interrupts, this helps interrupt processing threads to stop
calling in irq_thread().
For interrupt coalescing, according to the actual performance test, set
the count of CQ entries to 10 and the interrupt coalescing timeout
period to 10us based on the actual performance test.
Before and after interrupt coalescing is enabled, the 4K read/write
performance is improved by about 3%, and the 256K read/write performance
is basically the same.

the device is removed before controller reset or the PHY is not attached
to any device in directly attached scenario, the corresponding bit of
phy_state is not set. After controller reset done, the PHY is disabled.
The device cannot be identified even if user reconnect the disk.
Therefore, for PHYs that are not disabled by user, hisi_sas_phy_enable()

Hi Martin,
This patch series includes four patches that modify the UFS driver UIC
code without modifying the behavior of that code.
Please consider this patch series for the next merge window.
Thanks,
Bart.

Simplify __ufshcd_send_uic_cmd() by always initializing the
uic_cmd::done completion. This is fine since the time required to
initialize a completion is small compared to the time required to
process an UIC command.

In ufshcd_uic_cmd_compl(), there is code that dereferences 'cmd' with
and without checking the 'cmd' pointer. This confuses static source code
analyzers like Coverity and sparse. Since none of the code in
ufshcd_uic_cmd_compl() can do anything useful if 'cmd' is NULL, move the
'cmd' test near the start of this function.

The cpu_emergency_register_virt_callback() function is used
unconditionally by the x86 kvm code, but it is declared (and defined)
conditionally:
#if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD)
void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback);
...
leading to a build error when neither KVM_INTEL nor KVM_AMD support is
enabled:
arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’:
arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration]
12517 | cpu_emergency_register_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu);

arch/x86/kvm/x86.c:12522:9: error: implicit declaration of function ‘cpu_emergency_unregister_virt_callback’ [-Wimplicit-function-declaration]
12522 | cpu_emergency_unregister_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix the build by defining empty helper functions the same way the old
cpu_emergency_disable_virtualization() function was dealt with for the
same situation.
Maybe we could instead have made the call sites conditional, since the
callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak
fallback. I'll leave that to the kvm people to argue about, this at
least gets the build going for that particular config.

The DesignWare driver now has the correct ENABLE-ABORT sequence,

In the SynQuacer controller we now check for PCLK as an optional
clock, allowing ACPI to directly provide the clock rate.
The recent KEBA driver required a dependency fix in Kconfig.
The XIIC driver now has a corrected power suspend sequence.

Assorted minor syzbot fixes, and for bigger stuff:
- Fix two disk accounting rewrite bugs
- Disk accounting keys use the version field of bkey so that journal
replay can tell which updates have been applied to the btree. This is
set in the transaction commit path, after we've gotten our journal
reservation (and our time ordering), but the
BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay uses
was incorrectly skipping this for new updates generated prior to
journal replay.
This fixes the underlying cause of an assertion pop in
disk_accounting_read.
- A couple fixes for disk accounting + device removal. Checking if
acocunting replicas entries were marked in the superblock was being
done at the wrong point, when deltas in the journal could still zero
them out, and then additionally we'd try to add a missing replicas
entry to the superblock without checking if it referred to an invalid
(removed) device.
- A whole slew of repair fixes
- fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes
an infinite loop when repairing a filesystem with many snapshots
- fix incorrect transaction restart handling leading to occasional
"fsck counted ..." warnings"
- fix warning in __bch2_fsck_err() for bkey fsck errors
- check_inode() in fsck now correctly checks if the filesystem was
clean
- there shouldn't be pending logged ops if the fs was clean, we now
check for this
- remove_backpointer() doesn't remove a dirent that doesn't actually
point to the inode
