From e45ab8b8e5921fa3fa763a5e9729d90d342dcbcc Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" <darrick.wong@oracle.com> Date: Wed, 1 Aug 2018 17:06:44 -0500 Subject: [PATCH] xfs_repair: use libxfs extsize/cowextsize validation helpers Git-commit: db3d080b40ecce86ec6755a04544bbc59aa344da Patch-mainline: v4.18.0-rc1 References: bsc#1158509 Now that we've ported the extent size hint verifiers to libxfs, call them from xfs_repair instead of open-coding the checks. Tweak the repair message slightly to reflect the fact that we zero the field and clear the inode flag if the hint is garbage or is inconsistent with the inode flags. Signed-off-by: Darrick J.
