From 27e1f9d1cc87be4e53c6eb7158cafc21c4b85a14 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 5 Jun 2012 13:36:44 +0200 Subject: [PATCH] blkcg: drop local variable @q from blkg_destroy() blkg_destroy() caches @blkg->q in local variable @q. While there are two places which needs @blkg->q, only lockdep_assert_held() used the local variable leading to unused local variable warning if lockdep is configured out. Drop the local variable and just use @blkg->q directly.
