From 6519f708cc355c4834edbe1885c8542c0e7ef907 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" <darrick.wong@oracle.com> Date: Sun, 17 Nov 2019 10:36:52 -0800 Subject: [PATCH] xfs: report corruption only as a regular error Redefine XFS_IS_CORRUPT so that it reports corruptions only via xfs_corruption_report. Since these are on-disk contents (and not checks of internal state), we don't ever want to panic the kernel. This also amends the corruption report to recommend unmounting and running xfs_repair.
