If inode number is equal to the line number of locks which is first column in /proc/locks, generic/504 will match wrong number and get PASS. For example: ----------------------------------------------------------- inode 12 ... 12: FLOCK ADVISORY WRITE 1615 00:2e:37889 0 EOF ----------------------------------------------------------- We should match correct inode number by six column in /proc/locks.
