Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fix from James Bottomley: "One final fix before 4.8. There was a memory leak triggered by turning scsi mq off due to the fact that we assume on host release that the already running hosts weren't mq based because that's the state of the global flag (even though they were). Fix it by tracking this on a per host host basis" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: Avoid that toggling use_blk_mq triggers a memory leak
