[GIT PULL] First round of SCSI updates for the 3.5+ merge window

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-misc
