From d15b84590a1d2ec021ada00a0e67ee5851a0ea2b Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 29 Aug 2011 14:17:31 -0700 Subject: mac80211: Remove unnecessary OOM logging messages Removing unnecessary messages saves code and text. Site specific OOM messages are duplications of a generic MM out of memory message and aren't really useful, so just delete them. Signed-off-by: Joe Perches Signed-off-by: John W.
