== SRU Justification ==
Due to this bug, the module reference count will leak whenever you write to
/sys/fs/cgroup/blkio/blkio.throttle.* There is a script in the bug report
to reproduce the bug.
Commit 39a169b62b41 resolves this bug and was added to mainline in
v4.5-rc5. However, it was not cc'd to stable.
This commit is also needed in Trusty, but needs a minor backport. The Trusty
SRU will be sent separately.
== Fix ==

block: fix module reference leak on put_disk() call for cgroups throttle
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
