struct MPI2_RAID_SCSI_IO_REQUEST ends with a single SGL, but expects to
copy multiple. Add a flexible array member so the compiler can reason about
the size of the memcpy(). This will avoid the run-time false positive
warning:
memcpy: detected field-spanning write (size 128) of single field "&r1_cmd->io_request->SGL" at drivers/scsi/megaraid/megaraid_sas_fusion.c:3326 (size 16)
This change results in no binary output differences.

Mike Christie <michael.christie@oracle.com> says:
The following patches were made over Martin's scsi-staging/next
branch. They add a struct that contains optinal arguments to the
scsi_execute* functions. This will be needed for the patches that
allow the SCSI passthrough users to control retries because I'm adding
a new optional argument. I separated the 2 sets to make it easier to
review and post.

Since commit fc7a6209d571 ("bus: Make remove callback return
void") forces bus_type::remove be void-returned, it doesn't
make much sense for any bus based driver implementing remove
callbalk to return non-void to its caller.
As such, change the remove function for Hyper-V VMBus based
drivers to return void.

Move the SCSI execution functions to use a struct for passing in optional
args. This commit adds the new struct, temporarily converts scsi_execute()
and scsi_execute_req() ands a new helper, scsi_execute_cmd(), which takes
the scsi_exec_args struct.
There should be no change in behavior. We no longer allow users to pass in
any request->rq_flags value, but they were only passing in RQF_PM which we
do support by allowing users to pass in the BLK_MQ_REQ flags used by
blk_mq_alloc_request().
Subsequent commits will convert scsi_execute() and scsi_execute_req() users
to the new helpers then remove scsi_execute() and scsi_execute_req().

One-element arrays (and multi-element arrays being treated as dynamically
sized) are deprecated[1] and are being replaced with flexible array members
in support of the ongoing efforts to tighten the FORTIFY_SOURCE routines on
memcpy(), correctly instrument array indexing with UBSAN_BOUNDS, and to
globally enable -fstrict-flex-arrays=3.
Replace one-element arrays with flexible-array member in struct
mvumi_msg_frame, struct mvumi_rsp_frame, and struct mvumi_hs_header,
adjusting the explicit sizing calculations at the same time.
This results in no functional differences in binary output. An explicit add
is now folded into the size calculation:
│ mov 0x1070(%r14),%eax
│ - add $0x4,%eax
│ - movabs $0xfffffffdc,%rbx
│ + movabs $0xfffffffe0,%rbx
│ add %rax,%rbx

when refreshing port id
Currently the driver sets the port invalid if one phy in the port is not
enabled, which may cause issues in expander situation. In directly attached
situation, if phy up doesn't occur in time when refreshing port id, the
port is incorrectly set to invalid which will also cause disk lost.
Therefore set a port invalid only if there are no devices attached to the
port.

In a large SAN testing configuration, frequent target port toggle tests are
occasionally resulting in missing lun path rediscoveries. An outstanding
PRLI can be inflight when a target RSCN dissappearance occurs, causing the
driver to retry PRLIs using invalid rpi contexts.
Fix by verifying that an ndlp's state was not restarted from PRLI_ISSUE
due to an intermediate RSCN. If not in a valid state, early exit PRLI
completion handling.
The last follow up RSCN indicating target reappearance retriggers
PLOGI/PRLI with a valid rpi context and is expected to succeed in LUN path
rediscovery.

With faulty cables in PT2PT topology, an unintentional ndlp double kref
decrement can occur.
If a FLOGI request is outstanding before the link goes down, the missing
FLOGI_ACC causes an F_Port ndlp to remain in the UNUSED state. During link
down, lpfc_cleanup_rpis() is called and decrements an ndlp kref.
Additionally, when the driver later decides to abort the FLOGI, the FLOGI
completion handler decrements the ndlp kref a second time.
Remove duplicate clean up logic in lpfc_cleanup_rpis() because the updated
FLOGI completion handler already handles the ndlp kref decrement.

The disable_vport() path calls the discovery state machine on all ndlps,
puts them into NPR state, and then calls lpfc_cleanup_rpis() with the
remove flag set. This unintentionally decrements an ndlp's kref twice and
can result in premature release of an ndlp because
lpfc_dev_loss_tmo_handler() triggers clean up of the ndlp again later.
Remove redundant code in disable_vport() that sets all the ndlps to NPR,
and change the call to lpfc_cleanup_rpis() to not remove the ndlps.
lpfc_dev_loss_tmo_handler() will handle final removal of the ndlps.

If after an adapter reset the appearance of link is not recovered, the
devices are not rediscovered. This is result of a race condition between
adapter reset (abort_isp) and the topology scan. During adapter reset, the
ABORT_ISP_ACTIVE flag is set. Topology scan usually occurred after adapter
reset. In this case, the topology scan came earlier than usual where it
ran into problem due to ABORT_ISP_ACTIVE flag was still set.

not be connected. Reset session state to allow relogin logic to redrive
the connection.
