fs: ext4: skip journal state if fs has metadata_csum 2020-04-27T18:55:29+00:00 Arnaud Ferraris arnaud.ferraris@collabora.com 2020-04-22T10:43:44+00:00 7683b11098ded5087138d84e2e85078335a0cb72 As u-boot doesn't support the metadata_csum feature, writing to a filesystem with this feature enabled will fail, as expected. However, during the process, a journal state check is performed, which could result in: - a fs recovery if the fs wasn't umounted properly - the fs being marked dirty Both these cases result in a superblock change, leading to a mismatch between the superblock checksum and its contents. Therefore, Linux will consider the filesystem heavily corrupted and will require e2fsck to be run manually to boot. By bypassing the journal state check, this patch ensures the superblock won't be corrupted if the filesystem has metadata_csum feature enabled.
