Subject: [GIT PULL] SCSI fixes for 4.16-rc2
These are mostly fixes for problems with merge window code. In
addition we have one doc update (alua) and two dead code removals
(aiclib and octogon) a spurious assignment removal (csiostor) and a
performance improvement for storvsc involving better interrupt
spreading and increasing the command per lun handling.
[fixup over previous pull to drop one of the storvsc patches]
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Andrew Vasquez (1):
scsi: qedi: Fix truncation of CHAP name and secret
Bart Van Assche (3):
scsi: qla2xxx: Fix a locking imbalance in qlt_24xx_handle_els()
scsi: scsi_dh: Document alua_rtpg_queue() arguments
scsi: qla2xxx: Avoid triggering undefined behavior in qla2x00_mbx_completion()
Chad Dupuis (1):
scsi: bnx2fc: Fix check in SCSI completion handler for timed out request
Colin Ian King (1):
scsi: csiostor: remove redundant assignment to pointer 'ln'
Corentin Labbe (2):
scsi: Remove Makefile entry for oktagon files
scsi: aic7xxx: remove aiclib.c
Dan Carpenter (2):
scsi: mptfusion: Add bounds check in mptctl_hp_targetinfo()
scsi: sym53c8xx_2: iterator underflow in sym_getsync()
Himanshu Madhani (1):
scsi: qla2xxx: Fix incorrect handle for abort IOCB
Manish Rangankar (1):
scsi: qla4xxx: skip error recovery in case of register disconnect.
Meelis Roos (1):
scsi: aacraid: fix shutdown crash when init fails
Michael Kelley (EOSG) (1):
scsi: storvsc: Increase cmd_per_lun for higher speed devices
Nilesh Javali (1):
scsi: qedi: Cleanup local str variable
Quinn Tran (2):
scsi: qla2xxx: Fix double free bug after firmware timeout
scsi: qla2xxx: Fix memory corruption during hba reset test
Sujit Reddy Thumma (1):
scsi: ufs: Enable quirk to ignore sending WRITE_SAME command
Tomas Henzl (1):
scsi: mpt3sas: fix an out of bound write
Tyrel Datwyler (1):
scsi: ibmvfc: fix misdefined reserved field in ibmvfc_fcp_rsp_info
