From ec686c9239b4d472052a271c505d04dae84214cc Mon Sep 17 00:00:00 2001 From: Anurup m Date: Mon, 29 Apr 2013 15:05:52 -0700 Subject: [PATCH] fs/fscache/stats.c: fix memory leak 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().
