From 2ce4d50f9cfab40831eee5e51e950d5c4724994b Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 1 Apr 2012 14:38:43 -0700 Subject: cfq: collapse cfq.h into cfq-iosched.c block/cfq.h contains some functions which interact with blkcg; however, this is only part of it and cfq-iosched.c already has quite some #ifdef CONFIG_CFQ_GROUP_IOSCHED. With conf/stat handling being moved to specific policies, having these relay functions isolated in cfq.h doesn't make much sense. Collapse cfq.h into cfq-iosched.c for now. Let's split blkcg support properly later if necessary.
