Message-id: <20180111121151.13197-1-sxwjean@me.com> Date: Thu, 11 Jan 2018 20:11:51 +0800 From: Xiongwei Song <sxwjean@...com> To: darrick.wong@...cle.com, linux-xfs@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH] xfs: destroy mutex pag_ici_reclaim_lock before free xfs_perag_t structure The mutex pag_ici_reclaim_lock of xfs_perag_t structure is initialized in xfs_initialize_perag. If happen errors in xfs_initialize_perag, or free resources in xfs_free_perag, wo need to destroy the mutex before free perag.
