Commit d39df15851 ("scsi: iscsi: Have abort handler get ref to conn")
added iscsi_get_conn()/iscsi_put_conn() calls during abort handling but
then also changed the handling of the case where we detect an already
completed task where we now end up doing a goto to the common put/cleanup
code. This results in a iscsi_task use after free, because the common
cleanup code will do a put on the iscsi_task.
This reverts the goto and moves the iscsi_get_conn() to after we've checked
if the iscsi_task is valid.

When an FC-GS I/O is aborted by lpfc, the driver requires a node pointer
for a dereference operation. In the abort I/O routine, the driver miscasts
a context pointer to the wrong data type and overwrites a single byte
outside of the allocated space. This miscast is done in the abort I/O
function handler because the handler works on both FC-GS and FC-LS
commands. However, the code neglected to get the correct job location for
the node.
Fix this by acquiring the necessary node pointer from the correct job
structure depending on the I/O type.

The UFS driver uses blk_mq_tagset_busy_iter() when identifying task
management requests to complete, however blk_mq_tagset_busy_iter() doesn't
work.
blk_mq_tagset_busy_iter() only iterates requests dispatched by the block
layer. That appears as if it might have started since commit 37f4a24c24
("blk-mq: centralise related handling into blk_mq_get_driver_tag") which
removed 'data->hctx->tags->rqs[rq->tag] = rq' from blk_mq_rq_ctx_init()
which gets called:
blk_get_request
blk_mq_alloc_request
__blk_mq_alloc_request
blk_mq_rq_ctx_init
Since UFS task management requests are not dispatched by the block layer,
hctx->tags->rqs[rq->tag] remains NULL, and since blk_mq_tagset_busy_iter()
relies on finding requests using hctx->tags->rqs[rq->tag], UFS task
management requests are never found by blk_mq_tagset_busy_iter().
By using blk_mq_tagset_busy_iter(), the UFS driver was relying on internal
details of the block layer, which was fragile and subsequently got
broken. Fix by removing the use of blk_mq_tagset_busy_iter() and having the
driver keep track of task management requests.

Both cxgb4 and csiostor drivers run on their own independent Physical
Function. But when cxgb4 and csiostor are both being loaded in parallel via
modprobe, there is a race when firmware upgrade is attempted by both the
drivers.
When the cxgb4 driver initiates the firmware upgrade, it halts the firmware
and the chip until upgrade is complete. When the csiostor driver is coming
up in parallel, the firmware mailbox communication fails with timeouts and
the csiostor driver probe fails.
Add a module soft dependency on cxgb4 driver to ensure loading csiostor
triggers cxgb4 to load first when available to avoid the firmware upgrade
race.

This reverts commit a113eaaf86.
There are a couple of issues with the commit:
1. It causes deadlocks.
2. It causes the shost->eh_cmd_q list of failed requests not to be
processed, ever.
So revert it.
1. Deadlocks
The SCSI error handler runs with requests blocked beginning when
scsi_schedule_eh() sets SHOST_RECOVERY state, continuing through
scsi_error_handler() callback ->eh_strategy_handler() until
scsi_restart_operations() is called. By setting eh_strategy_handler to
ufshcd_err_handler, the patch changed the UFS error handler to run with
requests blocked, including PM requests, for the entire run of the error
handler.
That conflicts with UFS error handler existing synchronization with UFS
device PM operations. The UFS error handler synchronizes with runtime PM
by doing pm_runtime_get_sync() prior to blocking requests itself. It
synchronizes with system PM by use of hba->host_sem, again before blocking
requests itself. However, if requests are already blocked, then PM
operations will block. So:
the UFS error handler blocks waiting on PM
+ PM blocks waiting on SCSI PM requests to process or fail
+ PM requests are blocked waiting on error handling to finish
= deadlock
This happens both for runtime PM and system PM.
Prior to the patch, these deadlocks could not happen even if SCSI error
handling was running, because the presence of requests in shost->eh_cmd_q
would mean the queues could not be suspended, which would mean that, should
the UFS error handler run at the same time, it would not need to wait for
PM or vice versa.
Please note these scenarios are not just theoretical, they were found
during testing on a Samsung Galaxy Book S.
2. ->eh_strategy_handler() must process shost->eh_cmd_q list of failed
requests, as all other eh_strategy_handler's do except UFS error handler.
Refer for example: scsi_unjam_host(), ata_scsi_error() and
sas_scsi_recover_host().

This happens when the __vmalloc() failed. Consider we are reporting 4096
zones, then we will have "bufsize = roundup((4096 + 1) * 64,
SECTOR_SIZE)" = (513 * 512) = 262656. Then, __vmalloc() failure halves
the bufsize to 131328, which is no longer aligned to SECTOR_SIZE.
Use rounddown() to ensure the size is always aligned to SECTOR_SIZE and fix

The kernel test robot reported the following sparse warning:
".../lpfc_els.c:3984:25: sparse: sparse: cast from restricted __be16"
For the error being flagged, using be32_to_cpu() on a be16 data type, it
was simple enough. But a review of other elements and warnings were also
evaluated.
This patch corrected several items in the original patch:
- Using be32_to_cpu() on a be16 data type
- cpu_to_le32() used on a std uint32_t (CPU) data type.
Note: This is a byte array, but stored in LE layout by hardware at
32-bit boundaries. So it possibly needed conversion.
- Using cpu_to_le32() on a std uint16_t and assigned to a char typeA
- Using le32_to_cpu() on a le16 type
- Missing cpu_to_le16() on an assignment

The kernel test robot flagged an warning for ".../efc_device.c:932:6:
warning: cast to smaller integer type 'enum efc_nport_topology' from 'void
*'"
For the topology events, the "arg" field is generically defined as a void *
and is used to pass different arguments. Most of the arguments are pointers
to data structures. But for the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event, the
argument is an enum value, and the code is typecasting the void * to an
enum generating the warning.
Fix by converting the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event to pass a pointer
to the enum, thus it's a straight-forward pointer dereference in the event
handler.

Clang + -Wimplicit-fallthrough warns:

switch labels [-Wimplicit-fallthrough]
default:

drivers/scsi/st.c:3831:2: note: insert 'break;' to avoid fall-through
default:

break;
1 warning generated.
Clang's -Wimplicit-fallthrough is a little bit more pedantic than GCC's,
requiring every case block to end in break, return, or fallthrough, rather
than allowing implicit fallthroughs to cases that just contain break or
return. Add a break so that there is no more warning, as has been done all
over the tree already.

Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did the
following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
The latter one will cause a tiny merge issue with your tree, as there
was a last-minute fix for this in 5.14 in your tree, but the fixup
should be "obvious". If you want me to provide a fixed merge for this,
please let me know.
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs
users at once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue.

The caller of this function (parisc_driver_remove() in
arch/parisc/kernel/drivers.c) ignores the return value, so better don't
return any value at all to not wake wrong expectations in driver authors.
The only function that could return a non-zero value before was
ipmi_parisc_remove() which returns the return value of
ipmi_si_remove_by_dev(). Make this function return void, too, as for all
other callers the value is ignored, too.
Also fold in a small checkpatch fix for:
WARNING: Unnecessary space before function pointer arguments
+ void (*remove) (struct parisc_device *dev);

scsi: core: Fix hang of freezing queue between blocking and running device
Samsung KLUFG8RHDA-B2D1 does not clear the unit attention condition if the
length is zero. So go back to requesting all the sense data, as it was
before patch "scsi: ufs: Request sense data asynchronously". That is
simpler than creating and maintaining a quirk for affected devices.

clk_get_rate() returns unsigned long and currently this driver stores the
return value in u32 type, resulting the below warning:
Fixed smatch warnings:
drivers/scsi/ufs/ufs-exynos.c:286 exynos_ufs_get_clk_info()
warn: wrong type for 'ufs->mclk_rate' (should be 'ulong')
drivers/scsi/ufs/ufs-exynos.c:287 exynos_ufs_get_clk_info()
warn: wrong type for 'pclk_rate' (should be 'ulong')
