| Subject: CIFS: Fix a memory leak when a lease break comes |
| |
| 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. |
