From 77311139f364d7f71fc9ba88f59fd90e60205007 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Mon, 31 Oct 2011 17:08:05 -0700 Subject: [PATCH] mm/debug-pagealloc.c: use plain __ratelimit() instead of printk_ratelimit() printk_ratelimit() should not be used, because it shares ratelimiting state with all other unrelated printk_ratelimit() callsites.
