v4: drop xfs patch
revise comment update patch with latest proposed semantics
This is a small revision to the patchset I sent a little over a week
ago [1]. Since then, this has also garnered a LWN article [2], so I
won't go into great detail on the basic premise and rationale.
The biggest change here is that I've dropped the xfs patch. Dave Chinner
stated that they'd need to add a new on-disk field instead of modifying
the behavior of the existing di_changecount field [3]. I'll leave that
to the xfs devs, but this does mean that xfs will have "buggy" behavior
until that's done.
I've also sent a revised manpage patchset separately to make sure that
the semantics are acceptable [4]. That hasn't gotten a lot of comments,
so I'm operating under the assumption that the semantics proposed there
are acceptable to most.
