Can you please create a git tree mirror on git.kernel.org?

Hi Alex:

	I see that xfs,xfsprogs,xfstests,dmapi all have a mirror on
	git.kernel.org before kernel.org went down. Now, kernel.org goes on
	without the mirrors, so, can you create them now? I think someone
	will need them like me. Isn't it?

Thanks a lot
