| Subject: [PATCH] fs/fscache/stats.c: fix memory leak |
| |
| 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(). |
