Subject: [GIT PULL] final round of SCSI updates for the 4.16+ merge window
This is a set of minor (and safe changes) that didn't make the initial
pull request plus some bug fixes. The status handling code is actually
a running regression from the previous merge window which had an
incomplete fix (now reverted) and most of the remaining bug fixes are
for problems older than the current merge window.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Bart Van Assche (3):
scsi: core: Make scsi_result_to_blk_status() recognize CONDITION MET
scsi: core: Rename __scsi_error_from_host_byte() into scsi_result_to_blk_status()
Revert "scsi: core: return BLK_STS_OK for DID_OK in __scsi_error_from_host_byte()"
Ben Hutchings (2):
scsi: qla2xxx: Fix race condition between iocb timeout and initialisation
scsi: qla2xxx: Avoid double completion of abort command
Bill Kuzeja (1):
scsi: qla2xxx: Fix small memory leak in qla2x00_probe_one on probe failure
Colin Ian King (1):
scsi: core: remove redundant assignment to shost->use_blk_mq
Dan Carpenter (2):
scsi: cxgb4i: silence overflow warning in t4_uld_rx_handler()
scsi: dpt_i2o: Use after free in I2ORESETCMD ioctl
Dave Carroll (1):
scsi: aacraid: Insure command thread is not recursively stopped
Johannes Thumshirn (3):
scsi: qla2xxx: Correct setting of SAM_STAT_CHECK_CONDITION
scsi: qla2xxx: correctly shift host byte
scsi: scsi_dh: Don't look for NULL devices handlers by name
Ross Lagerwall (1):
scsi: devinfo: Add Microsoft iSCSI target to 1024 sector blacklist
