Here's a new version of the patch, against current Linus' git tree. The most
important change from the first one is the support of the bio-integrity

As with the previous version, it's been only mildly tested (creation of a
filesystem and basic file manipulation, over a loop device).

Thanks a lot,
		Alberto
