Hi,
another one (details available on request):
[ INFO: possible recursive locking detected ]
---------------------------------------------
nfsd/1566 is trying to acquire lock:
(&inode->i_mutex){--..}, at: [<c0334e0c>] mutex_lock+0x1c/0x20
but task is already holding lock:
(&inode->i_mutex){--..}, at: [<c0334e0c>] mutex_lock+0x1c/0x20
other info that might help us debug this:
2 locks held by nfsd/1566:
#0: (hash_sem){..--}, at: [<c01b292d>] exp_readlock+0xd/0x10
#1: (&inode->i_mutex){--..}, at: [<c0334e0c>] mutex_lock+0x1c/0x20
