From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6 Description of problem: When removing the "trusted.md5sum" xattr, audit does not produce FS_WATCH records for a watched file. Since audit does not produce PATH records for fremovexattr, this results in no filesystem object identity information for this syscall.
