Subject[PATCH 83/93] CIFS: Fix a memory leak when a lease break comes
Date
3.8.13.10 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Pavel Shilovsky <pshilovsky@samba.org>

commit 1a05096de82f3cd672c76389f63964952678506f upstream.

This happens when we receive a lease break from a server, then
find an appropriate lease key in opened files and schedule the
oplock_break slow work. lw pointer isn't freed in this case.
