From bfd279a868987e4bca7dc72a029e0fc50316d6df Mon Sep 17 00:00:00 2001 From: Hou Tao Date: Tue, 26 Jul 2016 17:13:42 +0800 Subject: [PATCH] blkcg: kill unused field nr_undestroyed_grps 'nr_undestroyed_grps' in struct throtl_data was used to count the number of throtl_grp related with throtl_data, but now throtl_grp is tracked by blkcg_gq, so it is useless anymore.
