Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2016-12-14T18:49:33+00:00

Pull SCSI updates from James Bottomley:
 "This update includes the usual round of major driver updates (ncr5380,
  lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).

  There's also an assortment of minor fixes, mostly in error legs or
  other not very user visible stuff. The major change is the
  pci_alloc_irq_vectors replacement for the old pci_msix_.. calls; this
  effectively makes IRQ mapping generic for the drivers and allows
  blk_mq to use the information"

scsi: libfc: Remove an unneeded condition

2016-11-25T15:07:00+00:00

We verified that resp_code is FC_SPP_RESP_ACK earlier so we don't need
to check again here.

scsi: libfc: fix seconds_since_last_reset miscalculation

2016-11-18T01:44:51+00:00

Commit 540eb1eef0ab ("scsi: libfc: fix seconds_since_last_reset calculation")
removed the use of 'struct timespec' from fc_get_host_stats(). This broke the
output of 'fcoeadm -s' after kernel 4.8-rc1.

scsi: fc: use bsg_job_done

2016-11-18T01:15:26+00:00

fc_bsg_jobdone() and bsg_job_done() are 1:1 copies now so use the
bsg-lib one instead of the FC private implementation.

scsi: change FC drivers to use 'struct bsg_job'

Change FC drivers to use 'struct bsg_job' from bsg-lib.h instead of
'struct fc_bsg_job' from scsi_transport_fc.h and remove 'struct
fc_bsg_job'.

scsi: libfc: don't set FC_RQST_STATE_DONE before calling fc_bsg_jobdone()

2016-11-18T01:15:25+00:00

Don't set FC_RQST_STATE_DONE before calling fc_bsg_jobdone() as
fc_bsg_jobdone() calls blk_complete_requeust() which raises a soft-IRQ
that ends up in fc_bsg_sofirq_done() and fc_bsg_softirq_done() sets the
FC_RQST_STATE_DONE flag.

scsi: fc: provide fc_bsg_to_rport() helper

2016-11-18T01:15:25+00:00

Provide fc_bsg_to_rport() helper that will become handy when we're
moving from struct fc_bsg_job to a plain struct bsg_job. Also move all
LLDDs to use the new helper.

scsi: fc: Export fc_bsg_jobdone and use it in FC drivers

2016-11-18T01:15:25+00:00

Export fc_bsg_jobdone so drivers can use it directly instead of doing
the round-trip via struct fc_bsg_job::job_done() and use it in the
LLDDs.  That way we can also unify the interfaces of fc_bsg_jobdone and
bsg_job_done.

As we've converted all LLDDs over to use fc_bsg_jobdone() directly, we
can remove the function pointer from struct fc_bsg_job as well.

scsi: don't use fc_bsg_job::request and fc_bsg_job::reply directly

2016-11-18T01:15:24+00:00

Don't use fc_bsg_job::request and fc_bsg_job::reply directly, but use
helper variables bsg_request and bsg_reply. This will be helpful when
transitioning to bsg-lib.
