ext2: support statx syscall
Since statx, every filesystem should fill the attributes/attributes_mask in routine getattr. But the generic_fillattr has not fill that, so add ext2_getattr to do this. This can fix generic/424 while testing ext2. Reviewed-by: zhangyi (F) <yi.zhang@huawei.com> Signed-off-by: yangerkun <yangerkun@huawei.com> Signed-off-by: Jan Kara <jack@suse.cz>
