From a84b50ceb7d640437d0dc28a2bef0d0de054de89 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 30 Mar 2011 17:51:36 -0700 Subject: sctp: Pass __GFP_NOWARN to hash table allocation attempts. Like DCCP and other similar pieces of code, there are mechanisms here to try allocating smaller hash tables if the allocation fails. So pass in __GFP_NOWARN like the others do instead of emitting a scary message. Reported-by: Dave Jones Signed-off-by: David S.
