From 2d008835ec2fcf6eef3285e41e62a5eabd1fe76b Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Thu, 11 Jul 2019 09:29:15 +0800 Subject: [PATCH] f2fs: improve print log in f2fs_sanity_check_ckpt() As Park Ju Hyung suggested: "I'd like to suggest to write down an actual version of f2fs-tools here as we've seen older versions of fsck doing even more damage and the users might not have the latest f2fs-tools installed." This patch give a more detailed info of how we fix such corruption to user to avoid damageable repair with low version fsck.
