Subject: block: move rq_qos_exit() into disk_release()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5ca7546fe317bd181ad55f623f6e522069c2e426;p=linux.git

block: move rq_qos_exit() into disk_release()

Keep all teardown of file system I/O related functionality in one place.
There can't be file system I/O in disk_release(), so it is safe to move
rq_qos_exit() there.
