[Jiri Slaby]

From: Ilya Dryomov <ilya.dryomov@xxxxxxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 7c6e6fc53e7335570ed82f77656cedce1502744e upstream.

It is important that both regular and lingering requests lists are
empty when the OSD is removed.
