If anyone has any objections, please let me know. ------------------ From: Miklos Szeredi 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.
