From bea548831b8cee347181132eacd8b9711dfced92 Mon Sep 17 00:00:00 2001 From: Jiang Biao Date: Thu, 19 Apr 2018 12:04:26 +0800 Subject: [PATCH] blkcg: small fix on comment in blkcg_init_queue The comment before blkg_create() in blkcg_init_queue() was moved from blkcg_activate_policy() by commit ec13b1d6f0a0457312e615, but it does not suit for the new context.
