If we're going to be able to emulate stat() with this, then st_blksize must be
determinable from whatever's in struct statx.  If you can provide something
better for stx_blksize and an algorithm for mapping that to st_blksize, then
please do so.

I can't give you tests to merge yet.  Given the amount of bikeshedding that's
taken place on this, I'm glad I *haven't* done the testsuite yet - it would
have much more than doubled the amount of work.  I *still* don't know what the
final form is going to be.  I've chucked out almost everything extra because
every bit has someone who argues with it - and this includes people who argue
against things that have to be there!

Further:

	warthog>ls xfstests-dev/doc
	CHANGES

The documentation is missing.  There's a bit in the top level README, but
there's a whole lot of information that *should* be there - and isn't.
