[ INFO: possible recursive locking detected ]
2.6.19-rc1 #1
---------------------------------------------
fuser/13370 is trying to acquire lock:
(&inode->i_mutex){--..}, at: [<ffffffff804b9c52>] mutex_lock+0x25/0x2a
but task is already holding lock:
(&inode->i_mutex){--..}, at: [<ffffffff804b9c52>] mutex_lock+0x25/0x2a
other info that might help us debug this:
1 lock held by fuser/13370:
#0: (&inode->i_mutex){--..}, at: [<ffffffff804b9c52>] mutex_lock+0x25/0x2a
