Pull more SCSI updates from James Bottomley:
 "This is a batch of changes that didn't make it in the initial pull
  request because the lpfc series had to be rebased to redo an incorrect
  split.

  It's basically driver updates to lpfc, target, bnx2fc and ufs with the
  rest being minor updates except the sr_block_release one which fixes a
  use after free introduced by the removal of the global mutex in the
  first patch set"

Pull SCSI updates from James Bottomley:
 "This series has a huge amount of churn because it pulls in Mauro's doc
  update changing all our txt files to rst ones.

  Excluding that, we have the usual driver updates (qla2xxx, ufs, lpfc,
  zfcp, ibmvfc, pm80xx, aacraid), a treewide update for scnprintf and
  some other minor updates.

  The major core change is Hannes moving functions out of the aacraid
  driver and into the core"

scsi: aacraid: do not overwrite retval in aac_reset_adapter()

2020-04-01T02:13:49+00:00

'retval' got assigned a value twice, causing the original value to be lost.

block: move struct partition out of genhd.h

2020-03-24T13:57:08+00:00

struct partition is the on-disk format of a MSDOS partition table entry.
Move it out of genhd.h into a new msdos_partition.h header and give it
a msdos_ prefix to avoid confusion.
Also move the magic number from block/partitions/msdos.h to the new
header so that it can be used by the SCSI drivers looking at the DOS
partition tables.

scsi: aacraid: Use scnprintf() for avoiding potential buffer overflow

2020-03-17T17:36:09+00:00

Since snprintf() returns the would-be-output size instead of the actual
output size, the succeeding calls may go beyond the given buffer limit.
Fix it by replacing with scnprintf().

scsi: aacraid: Disabling TM path and only processing IOP reset

2020-03-12T03:07:57+00:00

Fixes the occasional adapter panic when sg_reset is issued with -d, -t, -b
and -H flags.  Removal of command type HBA_IU_TYPE_SCSI_TM_REQ in
aac_hba_send since iu_type, request_id and fib_flags are not populated.
Device and target reset handlers are made to send TMF commands only when
reset_state is 0.

scsi: aacraid: use scsi_host_busy_iter() in get_num_of_incomplete_fibs()

2020-02-29T01:54:53+00:00

Use the SCSI midlayer helper to traverse the number of outstanding
commands. This also eliminates the last usage for the cmd_list
functionality so we can drop it.

scsi: aacraid: use scsi_host_busy_iter() to wait for outstanding commands

2020-02-29T01:54:52+00:00

Instead of traversing the list of possible commands by hands we should be
using scsi_host_busy_iter() to figure out if there are outstanding
commands.

scsi: aacraid: use scsi_host_(block,unblock) to block I/O

2020-02-29T01:54:51+00:00

Use scsi_host_block() and scsi_host_unblock() instead of
scsi_block_requests()/scsi_unblock_requests() to block and unblock I/O.
This has the advantage that the block layer will stop sending I/O to the
adapter instead of having the SCSI midlayer requeueing I/O internally.
