From 9e506f7adce8e6165a104d3d78fddd8ff0cdccf8 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Fri, 4 Jun 2010 14:15:04 -0700 Subject: kernel/: fix BUG_ON checks for cpu notifier callbacks direct call The commit 80b5184cc537718122e036afe7e62d202b70d077 ("kernel/: convert cpu notifier to return encapsulate errno value") changed the return value of cpu notifier callbacks. Those callbacks don't return NOTIFY_BAD on failures anymore. But there are a few callbacks which are called directly at init time and checking the return value. I forgot to change BUG_ON checking by the direct callers in the commit.
