Default device-mapper enhancements for 3.2

Please pull from:

http://people.redhat.com/agk/git/linux-dm for-linus

to get the following device-mapper enhancements for inclusion in 3.2.

The highlight here is thin provisioning. This includes a new snapshot
implementation that, unlike the existing implementation, performs well with
multiple snapshots of the same device (e.g. for backups).
More-detailed documentation is included in-tree.

The development of userspace LVM support is progressing well and and we
expect to have the first release of this out in the next month or so.
(To try this, people should check out git://sources.redhat.com/git/lvm2 and
follow lvm-devel@redhat.com.)

Thanks,
Alasdair

No. At least last time I tried, that redhat server is regular dumb
http, not the "git protocol over port-80". And it takes forever and is
annoying as hell.

Get a kernel.org account, or get a real server. Not that crap. It's unusable.

Steve Whitehouse has kindly stepped in to host this for me temporarily
while, like many other people, I'm waiting to reobtain an account.

So please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/steve/linux-dm.git master

to get the following device-mapper enhancements for inclusion in 3.2.

The highlight here is thin provisioning. This includes a new snapshot
implementation that, unlike the existing implementation, performs well with
multiple snapshots of the same device (e.g. for backups).
More-detailed documentation is included in-tree.
