Badness in mutex_destroy at kernel/mutex-debug.c:458

[Nicolas KOWALSKI <Nicolas.Kowalski@xxxxxxx>]

Hello,

On my 2.6.16.1 system, when I umount the XFS filesystem, I have this
message:

It does not seem to cause any harm. I can still mount it, and
xfs_check reports nothing.

Some filesystem informations:

corbeau:~# grep sda3 /proc/mounts
/dev/sda3 /local xfs rw,usrquota,logbufs=8 0 0

corbeau:~# xfs_info /local

Is this related to this previous message in the list ?

Is this fix pending for 2.6.17 ?
