If anyone has any objections, please let me know. ------------------ From: Pavel Shilovsky 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.
