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.
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 at redhat.com.)
Thanks,
Alasdair
