From a2ae4cc9a16e211c8a128ba10d22a85431f093ab Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Tue, 23 Nov 2010 18:18:37 -0500 Subject: inotify: stop kernel memory leak on file creation failure If inotify_init is unable to allocate a new file for the new inotify group we leak the new group. This patch drops the reference on the group on file allocation failure.
