Remove it. Also, replace blkio_list_lock with a mutex blkcg_pol_mutex and let it protect the whole [un]registration. This is to prepare for per-queue policy activation and doesn't cause any functional difference. Signed-off-by: Tejun Heo Cc: Vivek Goyal Signed-off-by: Jens Axboe --- Reading git-diff-tree failed
