Thank you. commit 626d548a8d145a032cff9237245f8ac9d9056ac1 Author: David S. Miller <[EMAIL PROTECTED]> Date: Fri Mar 2 12:49:23 2007 -0800 [AF_UNIX]: Test against sk_max_ack_backlog properly. This brings things inline with the sk_acceptq_is_full() bug fix. The limit test should be x >= sk_max_ack_backlog. Signed-off-by: David S.
