Description Joe Orton 2006-09-18 14:42:13 UTC
=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.17-1.2630.fc6 #1
-------------------------------------------------------
bash/14405 is trying to acquire lock:
 (sk_lock-AF_INET){--..}, at: [<c05dcaa1>] tcp_sendmsg+0x14/0x9bb

but task is already holding lock:
 (&inode->i_alloc_sem){--..}, at: [<c048aa27>] notify_change+0xe5/0x2c2

which lock already depends on the new lock.

(i686 kernel)
