[Xen-devel] [PATCH v1] Tmem cleanups/improvements for v4.8.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Hey!

This batch of fixes slowly marches toward ripping out pieces
of code in tmem that are hard to maintain and improve on code
that was orginacally developed.

I had hoped that I would have had the migration support all
working, but it took longer than I thought to get to this
point (and migration is still broken). And it may have become
a giant series too if I had it all worked out.

Anyhow please take a peek at the patches. The first
couple of them should be fairly easy. The rest are more of
squashing various subcommands in one.

Any advice, ideas, etc are more than welcome.

Thanks!
