Hi, In function __ext4_grp_locked_error, __save_error_info(sb, function, line) is called to save error info in super block block, but does not sync that information to disk to info the subsequence fsck after reboot. The reason, I guess maybe it is in locked state. My question is why not make a call ext4_commit_super(sb, 1) after ext4_unlock_group(sb, grp) and ext4_handle_error(sb), so that subsequence fsck after reboot is sure to be well informed. Forgive my naiveness. Thanks a lot
