Some background info included in commit log would be good, e.g. ext4
didn't support get/set label ioctl but we're going to add that support
in both kernel and e2fsprogs.

And I noticed the kernel patch is still in review, and has no comments
so far. So I'd like to wait and make sure the new ioctl will be accepted
first.

Thanks,
Eryu
