From b8a13d039cbf7aec3b486fc0ae3996a5449afed2 Mon Sep 17 00:00:00 2001 From: Weston Andros Adamson Date: Tue, 23 Oct 2012 10:43:43 -0400 Subject: [PATCH] SUNRPC: remove BUG_ON from bc_malloc Replace BUG_ON() with WARN_ON_ONCE() and NULL return - the caller will handle this like a memory allocation failure.
