Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI fixes from James Bottomley:
 "Two simple fixes, both of which cause I/O hangs.

  The storvsc one is from the hyper-v which can hang under certain hot
  add/remove conditions and the other is generally, where removing a
  target and a device in close proximity can result in the release
  method being executed twice (and subsequent list and other corruption
  and an eventual panic)"
