From 55b333253d5bcafbe187b50474e40789301c53c6 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 17 Oct 2007 21:21:26 -0700 Subject: [NET]: Introduce the sk_detach_filter() call Filter is attached in a separate function, so do the same for filter detaching. This also removes one variable sock_setsockopt(). Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
