3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anurup m <anurup.m@huawei.com>
commit ec686c9239b4d472052a271c505d04dae84214cc upstream.
There is a kernel memory leak observed when the proc file /proc/fs/fscache/stats is read.
The reason is that in fscache_stats_open, single_open is called and the respective release function is not called during release. Hence fix with correct release function - single_release().
