Merge git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (45 commits)
[SCSI] qla2xxx: Update version number to 8.03.00-k1.
[SCSI] qla2xxx: Add ISP81XX support.
[SCSI] qla2xxx: Use proper request/response queues with MQ instantiations.
[SCSI] qla2xxx: Correct MQ-chain information retrieval during a firmware dump.
[SCSI] qla2xxx: Collapse EFT/FCE copy procedures during a firmware dump.
[SCSI] qla2xxx: Don't pollute kernel logs with ZIO/RIO status messages.
[SCSI] qla2xxx: Don't fallback to interrupt-polling during re-initialization with MSI-X enabled.
[SCSI] qla2xxx: Remove support for reading/writing HW-event-log.
[SCSI] cxgb3i: add missing include
[SCSI] scsi_lib: fix DID_RESET status problems
[SCSI] fc transport: restore missing dev_loss_tmo callback to LLDD
[SCSI] aha152x_cs: Fix regression that keeps driver from using shared interrupts
[SCSI] sd: Correctly handle 6-byte commands with DIX
[SCSI] sd: DIF: Fix tagging on platforms with signed char
[SCSI] sd: DIF: Show app tag on error
[SCSI] Fix error handling for DIF/DIX
[SCSI] scsi_lib: don't decrement busy counters when inserting commands
[SCSI] libsas: fix test for negative unsigned and typos
[SCSI] a2091, gvp11: kill warn_unused_result warnings
[SCSI] fusion: Move a dereference below a NULL test
...
Fixed up trivial conflict due to moving the async part of sd_probe
around in the async probes vs using dev_set_name() in naming.
