From 920de804bca61f88643bc9171bcd06f1a56c6258 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 24 Nov 2008 00:09:29 -0800 Subject: net: Make sure BHs are disabled in sock_prot_inuse_add() The rule of calling sock_prot_inuse_add() is that BHs must be disabled. Some new calls were added where this was not true and this tiggers warnings as reported by Ilpo. Fix this by adding explicit BH disabling around those call sites, or moving sock_prot_inuse_add() call inside an existing BH disabled section. Signed-off-by: Eric Dumazet Signed-off-by: David S.
