From: Eryu Guan Subject: [PATCH v2 3/4] shared: test truncate orphan inodes when mounting extN Date: Fri, 3 Apr 2015 15:18:02 +0800 Message-ID: <1428045482-10722-1-git-send-email-eguan@redhat.com> References: <1428045351-10446-1-git-send-email-eguan@redhat.com> Cc: linux-ext4@vger.kernel.org, Eryu Guan , Lukas Czerner To: fstests@vger.kernel.org Return-path: In-Reply-To: <1428045351-10446-1-git-send-email-eguan@redhat.com> Sender: fstests-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org ext4 should hold i_mutex when truncating orhpan inodes, or a WARNING would be triggered. This commit fixed this issue. 721e3eb ext4: lock i_mutex when truncating orphan inodes Though it's an ext4 specific issue, there's no harm to test on ext2/3 too, as debugfs is used to set orphan inode list. This test is based on a script from Lukas Czerner.
