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:
"The most important feature of this patch set is the new async
infrastructure that makes sure async_synchronize_full() synchronizes
all domains and allows us to remove all the hacks (like having
scsi_complete_async_scans() in the device base code) and means that
the async infrastructure will "just work" in future.
The rest is assorted driver updates (aacraid, bnx2fc, virto-scsi,
megaraid, bfa, lpfc, qla2xxx, qla4xxx) plus a lot of infrastructure
work in sas and FC.
Signed-off-by: James Bottomley <JBottomley@Parallels.com>"
