Subject: [ 026/110] CIFS: Fix a memory leak when a lease break comes
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pavel Shilovsky <pshilovsky@...ba.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.
