[dm-devel] [RFC] device-mapper v4 ioctl interface implementation

[Joe Thornber <thornber sistina com>]

Following on from the header file for the v4 ioctl interface that I
posted a couple of weeks ago, here is the first cut at the
implementation (3 patches posted as a follow up to this mail).  I hope
the v1 interface can be retired before 2.6.  Tools are not yet
available to drive this, but should be later this week.

Thoughts ?
