[ PATCH ] Memory leak fix for bug 57101.

[Anurup m]

Hi All,

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 respective release function is not called during release.
Hence fix with correct release function - single_release. The patch is as below
