# Merge: 1104bd96eb2a 61cce6f6eece
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
#     
#     Pull SCSI fixes from James Bottomley:
#      "This is two simple target fixes and one discard related I/O starvation
#       problem in sd.
#     
#       The discard problem occurs because the discard page doesn't have a
#       mempool backing so if the allocation fails due to memory pressure, we
#       then lose the forward progress we require if the writeout is on the
#       same device. The fix is to back it with a mempool"
#     
#     * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
#       scsi: sd: use mempool for discard special page
#       scsi: target: iscsi: cxgbit: add missing spin_lock_init()
