Subject: lockdep: possible circular locking dependency detected on umount
 ext3 mount point

Hello,

I apologize if it's already reported, but quick search in LKML archive 
didn't find anything like that.

After some dbench runs on ext3 partition, mounted on /mnt, then quickly 
umount /mnt, lockdep reported possible circular locking dependency 
detected. See attach for the complete message. Kernel is 2.6.23. I can 
provide more info, if needed.

Regards,
Vlad
