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.

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().

Asutosh Das <quic_asutoshd@quicinc.com> says:
This patch series is an implementation of UFS Multi-Circular Queue.
Please consider this series for next merge window. This
implementation has been verified on a Qualcomm & MediaTek platform.
UFS Multi-Circular Queue (MCQ) has been added in UFSHCI v4.0 to
improve storage performance. The implementation uses the shared
tagging mechanism so that tags are shared among the hardware
queues. The number of hardware queues is configurable. This series
doesn't include the ESI implementation for completion handling.

As Event Specific Interrupt message format is not defined in UFSHCI JEDEC
specs, and the ESI handling highly depends on how the format is designed,
hence add a vendor specific ops such that SoC vendors can configure their
own ESI handlers. If ESI vops is not provided or returning error, go with
the legacy (central) interrupt way.

Add support for completing requests from Completion Queue. Some host
controllers support vendor specific registers that provide a bitmap of all
CQs which have at least one completed CQE. Add this support. The MCQ
specification doesn't provide the Task Tag or its equivalent in the
Completion Queue Entry. So use an indirect method to find the Task Tag
from the Completion Queue Entry.

to 255. In multi-circular queue mode, this may not be enough. The
specification provides EXT_IID which can be used to increase the number of

One-element arrays (and multi-element arrays being treated as dynamically

in support of the ongoing efforts to tighten the FORTIFY_SOURCE routines on
memcpy(), correctly instrument array indexing with UBSAN_BOUNDS, and to

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

The driver accessed wr_object pointer data, which was initialized into
mailbox payload memory, after the mailbox object was released back to the
mailbox pool.
Fix by moving the mailbox free calls to the end of the routine ensuring
that we don't reference internal mailbox memory after release.

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.

During I/O, the following warning message occasionally appears:
DMA-API: lpfc 0000:04:00.0: mapping sg segment longer than device claims to
support [len=131072] [max=65536]
The HBA is capable of supporting 131,072 bytes, so notify DMA layer via the
dma_set_max_seg_size() API during hba initialization.

The local variables called curr_data are incremented, but not actually used
for anything so they are removed.
The return value of lpfc_sli4_poll_eq is not used anywhere and is not
called outside of lpfc_sli.c. Thus, its declaration is removed from
lpfc_crtn.h Also, lpfc_sli4_poll_eq's path argument is not used in the
routine so it is removed along with corresponding macros.
