From 5bc0b3bfa758e4ae49c94e31c1edb9a5f10a8060 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 25 Nov 2008 13:53:27 -0800 Subject: [PATCH] net: Make sure BHs are disabled in sock_prot_inuse_add() prot->destroy is not called with BH disabled. So we must add explicit BH disable around call to sock_prot_inuse_add() in sctp_destroy_sock() Signed-off-by: Eric Dumazet Signed-off-by: David S.
