From 32e380aedc3de454c06ce1c254fe3bea35a676e1 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 5 Mar 2012 13:14:54 -0800 Subject: blkcg: make CONFIG_BLK_CGROUP bool Block cgroup core can be built as module; however, it isn't too useful as blk-throttle can only be built-in and cfq-iosched is usually the default built-in scheduler. Scheduled blkcg cleanup requires calling into blkcg from block core. To simplify that, disallow building blkcg as module by making CONFIG_BLK_CGROUP bool. If building blkcg core as module really matters, which I doubt, we can revisit it after blkcg API cleanup. -v2: Vivek pointed out that IOSCHED_CFQ was incorrectly updated to depend on BLK_CGROUP. Fixed.
