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. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
