It's mentioned on the Xen4.0 wiki page since that's when the feature was developed. http://wiki.xen.org/xenwiki/Xen4.0 .
I think it was originally submitted by Novell developers, who wrote it for SLES11. Later Jeremy (pvops kernel maintainer) submitted it for upstream kernel inclusion, and it got included to upstream Linux in 2.6.36. It's also included in xen.git xen/stable-2.6.32.x branch.
I've tested it myself, and all you need to do is to resize the LVM volume in dom0, and domU will detect the size change.
