Message-ID: <20230213080514.535568-3-zhanchengbin1@huawei.com> Date: Mon, 13 Feb 2023 16:05:14 +0800 From: zhanchengbin <zhanchengbin1@...wei.com> To: <tytso@....edu>, <jack@...e.com> CC: <linux-ext4@...r.kernel.org>, <yi.zhang@...wei.com>, <linfeilong@...wei.com>, <liuzhiqiang26@...wei.com>, zhanchengbin <zhanchengbin1@...wei.com>, kernel test robot <lkp@...el.com> Subject: [PATCH v5 2/2] ext4: clear the verified flag of the modified leaf or idx if error Clear the verified flag from the modified bh when failed in ext4_ext_rm_idx or ext4_ext_correct_indexes. In this way, the start value of the logical block itself and its parents' will be checked in ext4_valid_extent_entries.
