Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley: "This patch set is a set of driver updates (ufs, zfcp, lpfc, mpt2/3sas, qla4xxx, qla2xxx [adding support for ISP8044 + other things]). We also have a new driver: esas2r which has a number of static checker problems, but which I expect to resolve over the -rc course of 3.12 under the new driver exception. We also have the error return that were discussed at LSF" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (118 commits) [SCSI] sg: push file descriptor list locking down to per-device locking [SCSI] sg: checking sdp->detached isn't protected when open [SCSI] sg: no need sg_open_exclusive_lock [SCSI] sg: use rwsem to solve race during exclusive open [SCSI] scsi_debug: fix logical block provisioning support when unmap_alignment != 0 [SCSI] scsi_debug: fix endianness bug in sdebug_build_parts() [SCSI] qla2xxx: Update the driver version to 8.06.00.08-k. [SCSI] qla2xxx: print MAC via %pMR. [SCSI] qla2xxx: Correction to message ids. [SCSI] qla2xxx: Correctly print out/in mailbox registers. [SCSI] qla2xxx: Add a new interface to update versions. [SCSI] qla2xxx: Move queue depth ramp down message to i/o debug level. [SCSI] qla2xxx: Select link initialization option bits from current operating mode. [SCSI] qla2xxx: Add loopback IDC-TIME-EXTEND aen handling support. [SCSI] qla2xxx: Set default critical temperature value in cases when ISPFX00 firmware doesn't provide it [SCSI] qla2xxx: QLAFX00 make over temperature AEN handling informational, add log for normal temperature AEN [SCSI] qla2xxx: Correct Interrupt Register offset for ISPFX00 [SCSI] qla2xxx: Remove handling of Shutdown Requested AEN from qlafx00_process_aen(). [SCSI] qla2xxx: Send all AENs for ISPFx00 to above layers. [SCSI] qla2xxx: Add changes in initialization for ISPFX00 cards with BIOS ...
