Long Li 0ed8810276 scsi: storvsc: setup 1:1 mapping between hardware queue and CPU queue
storvsc doesn't use a dedicated hardware queue for a given CPU queue. When
issuing I/O, it selects returning CPU (hardware queue) dynamically based on
vmbus channel usage across all channels.

This patch advertises num_present_cpus() as number of hardware queues. This
will have upper layer setup 1:1 mapping between hardware queue and CPU
queue and avoid unnecessary locking when issuing I/O.

Stanley Chu f51913eef2 scsi: ufs: skip shutdown if hba is not powered
In some cases, hba may go through shutdown flow without successful
initialization and then make system hang.

For example, if ufshcd_change_power_mode() gets error and leads to
ufshcd_hba_exit() to release resources of the host, future shutdown flow
may hang the system since the host register will be accessed in unpowered
state.

To solve this issue, simply add checking to skip shutdown for above kind of
situation.

Laurence Oberman c9c5374937 scsi: bnx2fc: Handle scope bits when array returns BUSY or TSF
The qla2xxx driver had this issue as well when the newer array firmware
returned the retry_delay_timer in the fcp_rsp.  The bnx2fc is not handling
the masking of the scope bits either so the retry_delay_timestamp value
lands up being a large value added to the timer timestamp delaying I/O for
up to 27 Minutes.  This patch adds similar code to handle this to the
bnx2fc driver to avoid the huge delay.

Max Gurtovoy 54d4e6ab91 block: centralize PI remapping logic to the block layer
Currently t10_pi_prepare/t10_pi_complete functions are called during the
NVMe and SCSi layers command preparetion/completion, but their actual
place should be the block layer since T10-PI is a general data integrity
feature that is used by block storage protocols. Introduce .prepare_fn
and .complete_fn callbacks within the integrity profile that each type
can implement according to its needs.

Pull LED updates from Jacek Anaszewski:
 "In this cycle we've finally managed to contribute the patch set
  sorting out LED naming issues. Besides that there are many changes
  scattered among various LED class drivers and triggers.

  LED naming related improvements:

   - add new 'function' and 'color' fwnode properties and deprecate
     'label' property which has been frequently abused for conveying
     vendor specific names that have been available in sysfs anyway

   - introduce a set of standard LED_FUNCTION* definitions

   - introduce a set of standard LED_COLOR_ID* definitions

   - add a new {devm_}led_classdev_register_ext() API with the
     capability of automatic LED name composition basing on the
     properties available in the passed fwnode; the function is
     backwards compatible in a sense that it uses 'label' data, if
     present in the fwnode, for creating LED name

   - add tools/leds/get_led_device_info.sh script for retrieving LED
     vendor, product and bus names, if applicable; it also performs
     basic validation of an LED name

   - update following drivers and their DT bindings to use the new LED
     registration API:

        - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
          leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt

  Other LED class improvements:

   - replace {devm_}led_classdev_register() macros with inlines

   - allow to call led_classdev_unregister() unconditionally

   - switch to use fwnode instead of be stuck with OF one

  LED triggers improvements:

   - led-triggers:
        - fix dereferencing of null pointer
        - fix a memory leak bug

   - ledtrig-gpio:
        - GPIO 0 is valid

  Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
  more complete driver exists, based on a generic driver for the AMD
  SOCs gpio-controller, supporting LEDs as well other devices:

   - drop profile field from priv data

   - drop iosize field from priv data

   - drop enum_apu_led_platform_types

   - drop superseeded apu2/3 led support

   - add pr_fmt prefix for better log output

   - fix error message on probing failure

  Other misc fixes and improvements to existing LED class drivers:

   - leds-ns2, leds-max77650:
        - add of_node_put() before return

   - leds-pwm, leds-is31fl32xx:
        - use struct_size() helper

   - leds-lm3697, leds-lm36274, leds-lm3532:
        - switch to use fwnode_property_count_uXX()

   - leds-lm3532:
        - fix brightness control for i2c mode
        - change the define for the fs current register
        - fixes for the driver for stability
        - add full scale current configuration
        - dt: Add property for full scale current.
        - avoid potentially unpaired regulator calls
        - move static keyword to the front of declarations
        - fix optional led-max-microamp prop error handling

   - leds-max77650:
        - add of_node_put() before return
        - add MODULE_ALIAS()
        - Switch to fwnode property API

   - leds-as3645a:
        - fix misuse of strlcpy

   - leds-netxbig:
        - add of_node_put() in netxbig_leds_get_of_pdata()
        - remove legacy board-file support

   - leds-is31fl319x:
        - simplify getting the adapter of a client

   - leds-ti-lmu-common:
        - fix coccinelle issue
        - move static keyword to the front of declaration

   - leds-syscon:
        - use resource managed variant of device register

   - leds-ktd2692:
        - fix a typo in the name of a constant

   - leds-lp5562:
        - allow firmware files up to the maximum length

   - leds-an30259a:
        - fix typo

   - leds-pca953x:
        - include the right header"

Xiang Chen e74006edd0 scsi: hisi_sas: Fix the conflict between device gone and host reset
When device gone, it will check whether it is during reset, if not, it will
send internal task abort. Before internal task abort returned, reset
begins, and it will check whether SAS_PHY_UNUSED is set, if not, it will
call hisi_sas_init_device(), but at that time domain_device may already be
freed or part of it is freed, so it may referenece null pointer in
hisi_sas_init_device(). It may occur as follows:

    thread0				thread1
hisi_sas_dev_gone()
    check whether in RESET(no)
    internal task abort
				    reset prep
				    soft_reset
				    ... (part of reset_done)
    internal task abort failed
    release resource anyway
    clear_itct
    device->lldd_dev=NULL
				    hisi_sas_reset_init_all_device
					check sas_dev->dev_type is SAS_PHY_UNUSED and
					!device
    set dev_type SAS_PHY_UNUSED
    sas_free_device
					hisi_sas_init_device
					...

Semaphore hisi_hba.sema is used to sync the processes of device gone and
host reset.

To solve the issue, expand the scope that semaphore protects and let them
never occur together.

And also some places will check whether domain_device is NULL to judge
whether the device is gone. So when device gone, need to clear
sas_dev->sas_device.

At hisi_sas_debug_I_T_nexus_reset(), we call sas_phy_reset() to reset a
phy. But if the phy is disabled, sas_phy_reset() will directly return
-ENODEV without issue a phy reset request.

If so, We can directly return -ENODEV to libsas before issue a phy
reset.

Matt Lupfer 5ff8437214 scsi: virtio_scsi: unplug LUNs when events missed
The event handler calls scsi_scan_host() when events are missed, which will
hotplug new LUNs.  However, this function won't remove any unplugged LUNs.
The result is that hotunplug doesn't work properly when the number of
unplugged LUNs exceeds the event queue size (currently 8).

Scan existing LUNs when events are missed to check if they are still
present.  If not, remove them.

rdac_failover_get(), which leads to some random data getting to the

INVALID FIELD IN CDB. Code before commit 3278255741 was not affected, as
it called blk_rq_set_block_pc().

Fix this by zeroing out the cdb first.

James Smart 4fb86a6bc5 scsi: lpfc: Fix reset recovery paths that are not recovering
A recent patch unconditionally marks the hba as in error as part of
resetting the adapter. The driver flow that called the adapter reset was a
recovery path, which expects the adapter to not be in an error state in
order to finish the recovery.  Given the new error state being set, the
recovery fails and the adapter is left in limbo.

Revise the adapter reset routine so that it will only mark the adapter in
error if it was unable to reset the adapter.
