Before this patch, SB_RDONLY is set, so remount,rw returned -EROFS. With this patch, sb_rdonly(sb) is false, so remount,rw skips the check and return success even though writes are rejected with -EROFS. I think that the condition should be test NVolErrors(), for example if ((sb_rdonly(sb) || NVolErrors(vol)) && !(fc->sb_flags & SB_RDONLY)) { -- Thanks, Hyunchul
