Re: [git pull] device-mapper patches for 2.6.31-rc1

[Mike Snitzer <snitzer@redhat.com>]

Linus,

Given that you recently expressed your intent to release -rc1 soon:
http://lkml.org/lkml/2009/6/23/618

Alasdair is at linuxtag all week, so I figured I'd point out his DM pull
request from a couple days ago in case you missed it.

Thanks,
Mike
