Subject: stale POSIX flock

Hello,
I've got a strange bug:
POSIX lock is left in system after process termination.
After some debugging I found that filp->f_count entry at the end of
sys_fctl64 function is 1(???) and subsequent call to fput releases
file sturcture, but leaves POSIX lock.
I've added check for FL_POSIX flag to locks_remove_flock and the problem stoped.
This bug happens very often on my environment, but user mode setup is
a multi-process/multi-threaded application, so I have no clue how to
reduce it to a simple testing program.
I work with enterprise linux 3, IBM xSeries345, Pentium4 3000 x2, 2GB RAM
