If adding a mount or inode mark failed fanotify_free_mark() is called explicitly. But at this time the mark has already been put into the destroy list of the fsnotify_mark kernel thread. If the thread is too slow it will try to decrease the reference of a mark, that has already been freed by fanotify_free_mark(). (If its fast enough it will only decrease the marks ref counter from 2 to 1 - note that the counter has been increased to 2 in add_mark() - which has practically no effect.) This patch fixes the ref counting by not calling free_mark() explicitly, but decreasing the ref counter and rely on the fsnotify_mark thread to cleanup in case adding the mark has failed.
