6f4b98147b devlink: make health report on unregistered instance warn just once
Devlink health is involved in error recovery. Machines in bad
state tend to be fairly unreliable, and occasionally get stuck
in error loops. Even with a reasonable grace period devlink health
may get a thousand reports in an hour.

In case of reporting on an unregistered devlink instance
the subsequent reports don't add much value. Switch to
WARN_ON_ONCE() to avoid flooding dmesg and fleet monitoring
dashboards.

622ab65634 sfc: fix error unwinds in TC offload
Failure ladders weren't exactly unwinding what the function had done up
 to that point; most seriously, when we encountered an already offloaded
 rule, the failure path tried to remove the new rule from the hashtable,
 which would in fact remove the already-present 'old' rule (since it has
 the same key) from the table, and leak its resources.

8764bd0fa5 net/mlx5: Fix setting of irq->map.index for static IRQ case
When dynamic IRQ allocation is not supported all IRQs are allocated up
front in mlx5_irq_table_create() instead of dynamically as part of
mlx5_irq_alloc(). In the latter dynamic case irq->map.index is set
via the mapping returned by pci_msix_alloc_irq_at(). In the static case
and prior to commit 1da438c0ae ("net/mlx5: Fix indexing of mlx5_irq")
irq->map.index was set in mlx5_irq_alloc() twice once initially to 0 and
then to the requested index before storing in the xarray. After this
commit it is only set to 0 which breaks all other IRQ mappings.

Fix this by setting irq->map.index to the requested index together with
irq->map.virq and improve the related comment to make it clearer which
cases it deals with.

1c4c769cdf net/mlx5: Remove rmap also in case dynamic MSIX not supported
mlx5 add IRQs to rmap upon MSIX request, and mlx5 remove rmap from
MSIX only if msi_map.index is populated. However, msi_map.index is
populated only when dynamic MSIX is supported. This results in freeing
IRQs without removing them from rmap, which triggers the bellow
WARN_ON[1].

rmap is a feature which have no relation to dynamic MSIX.
Hence, remove the check of msi_map.index when removing IRQ from rmap.

fe8637f770 scsi: ufs: core: Increase the START STOP UNIT timeout from one to ten seconds
One UFS vendor asked to increase the UFS timeout from 1 s to 3 s.  Another
UFS vendor asked to increase the UFS timeout from 1 s to 10 s.  Hence this
patch that increases the UFS timeout to 10 s. This patch can cause the
total timeout to exceed 20 s, the Android shutdown timeout.  This is fine
since the loop around ufshcd_execute_start_stop() exists to deal with unit
attentions and because unit attentions are reported quickly.

In preparation for adding MCQ error handler support, update the MCQ code to

ufshcd_mcq_poll_cqe_nolock(). This is to keep synchronization between MCQ
interrupt and error handler contexts because both need to access the MCQ

7aa12d2fe8 scsi: ufs: core: Update the ufshcd_clear_cmds() functionality
In the ufshcd_clear_cmds(), the 2nd parameter would be the bit mask of the
command to be cleared in the transfer request door bell register. This bit
mask mechanism does not scale well in MCQ mode when the queue depth becomes
much greater than 64. Change the 2nd parameter to the function to be the
task_tag number of the corresponding bit to be cleared in the door bell
register.  By doing so, MCQ mode with a large queue depth can reuse this
function.

Since the behavior of this function is changed from handling multiple
commands into a single command, rename ufshcd_clear_cmds() into
ufshcd_clear_cmd().

9914a3d033 scsi: lpfc: Revise NPIV ELS unsol rcv cmpl logic to drop ndlp based on nlp_state
When NPIV ports are zoned to devices that support both initiator and target
mode, a remote device's initiated PRLI results in unintended final kref
clean up of the device's ndlp structure.  This disrupts NPIV ports'
discovery for target devices that support both initiator and target mode.

Modify the NPIV lpfc_drop_node clause such that we allow the ndlp to live
so long as it was in NLP_STE_PLOGI_ISSUE, NLP_STE_REG_LOGIN_ISSUE, or
NLP_STE_PRLI_ISSUE nlp_state.  This allows lpfc's issued PRLI completion
routine to determine if the final kref clean up should execute rather than
a remote device's issued PRLI.
