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. Reported-by: Vegard Nossum <vegard.nossum@gmail.com> cc: stable@kernel.org Signed-off-by: Eric Paris <eparis@redhat.com>
