Pull SCSI updates from James Bottomley: "This series consists of the usual driver updates (ufs, qla2xxx, target, smartpqi, lpfc, mpt3sas). The core change causing the most churn was replacing the command request field request with a macro, allowing us to offset map to it and remove the redundant field; the same was also done for the tag field. The most impactful change is the final removal of scsi_ioctl, which has been deprecated for over a decade" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (293 commits) scsi: ufs: Fix ufshcd_request_sense_async() for Samsung KLUFG8RHDA-B2D1 scsi: ufs: ufs-exynos: Fix static checker warning scsi: mpt3sas: Use the proper SCSI midlayer interfaces for PI scsi: lpfc: Use the proper SCSI midlayer interfaces for PI scsi: lpfc: Copyright updates for 14.0.0.1 patches scsi: lpfc: Update lpfc version to 14.0.0.1 scsi: lpfc: Add bsg support for retrieving adapter cmf data scsi: lpfc: Add cmf_info sysfs entry scsi: lpfc: Add debugfs support for cm framework buffers scsi: lpfc: Add support for maintaining the cm statistics buffer scsi: lpfc: Add rx monitoring statistics scsi: lpfc: Add support for the CM framework scsi: lpfc: Add cmfsync WQE support scsi: lpfc: Add support for cm enablement buffer scsi: lpfc: Add cm statistics buffer support scsi: lpfc: Add EDC ELS support scsi: lpfc: Expand FPIN and RDF receive logging scsi: lpfc: Add MIB feature enablement support scsi: lpfc: Add SET_HOST_DATA mbox cmd to pass date/time info to firmware scsi: fc: Add EDC ELS definition ...

RDMA/rtrs-clt: Fix counting inflight IO

2021-08-22T22:22:59+00:00

There are mis-match at counting inflight IO after changing the multipath policy. For example, we started fio test with round-robin policy and then we changed the policy to min-inflight. IOs created under the RR policy is finished under the min-inflight policy and inflight counter only decreased. So the counter would be negative value. And also we started fio test with min-inflight policy and changed the policy to the round-robin. IOs created under the min-inflight policy increased the inflight IO counter but the inflight IO counter was not decreased because the policy was the round-robin when IO was finished. So it should count IOs only if the IO is created under the min-inflight policy. It should not care the policy when the IO is finished. This patch adds a field mp_policy in struct rtrs_clt_io_req and stores the multipath policy when an object of rtrs_clt_io_req is created. Then rtrs-clt checks the mp_policy of only struct rtrs_clt_io_req instead of the struct rtrs_clt.

RDMA/rtrs: Remove all likely and unlikely

2021-08-22T22:22:59+00:00

The IO performance test with fio after swapping the likely and unlikely macros in all if-statement shows no difference. They do not help for the performance of rtrs. Thanks to Haakon Bugge for the test scenario. The fio test did random read on 32 rnbd devices and 64 processes.
