3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miklos Szeredi <mszeredi@suse.cz>
commit 799b601451b21ebe7af0e6e8f6e2ccd4683c5064 upstream.
Audit rules disappear when an inode they watch is evicted from the cache. This is likely not what we want.
The guilty commit is "fsnotify: allow marks to not pin inodes in core", which didn't take into account that audit_tree adds watches with a zero mask.
Adding any mask should fix this.
