hi!

I found the following when running 2.6.18-rc3 and reiserfs.

Please cc me as I'm not on the mailing list.

=============================================
[ INFO: possible recursive locking detected ]
---------------------------------------------
kdm/4199 is trying to acquire lock:
(&inode->i_mutex){--..}, at: [<c0297b95>] mutex_lock+0x21/0x24

but task is already holding lock:
(&inode->i_mutex){--..}, at: [<c0297b95>] mutex_lock+0x21/0x24

other info that might help us debug this:
1 lock held by kdm/4199:
#0: (&inode->i_mutex){--..}, at: [<c0297b95>] mutex_lock+0x21/0x24
