Jan Kara c92dc85684 ext4: defer saving error info from atomic context ... When filesystem inconsistency is detected with group locked, we currently try to modify superblock to store error there without blocking. However this can cause superblock checksum failures (or DIF/DIX failure) when the superblock is just being written out. Make error handling code just store error information in ext4_sb_info structure and copy it to on-disk superblock only in ext4_commit_super(). In case of error happening with group locked, we just postpone the superblock flushing to a workqueue. [ Added fixup so that s_first_error_* does not get updated after the file system is remounted. Also added fix for syzbot failure. - Ted ] Signed-off-by: Jan Kara <jack@suse.cz> Link: https://lore.kernel.org/r/20201127113405.26867-8-jack@suse.cz Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: Hillf Danton <hdanton@sina.com> Reported-by: syzbot+9043030c040ce1849a60@syzkaller.appspotmail.com		2020-12-22 13:07:49 -05:00
