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

Pull SCSI fixes from James Bottomley:
 "Two patches in driver frameworks. The iscsi one corrects a bug induced
  by a BPF change to network locking and the other is a regression we
  introduced"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: iscsi: iscsi_tcp: Avoid holding spinlock while calling getpeername()
  scsi: target: Fix lun lookup for TARGET_SCF_LOOKUP_LUN_FROM_TAG case
