The patches are in my staging tree --
git://git.kernel.org/pub/scm/linux/kernel/git/ostr/linux.git,
for-linus-4.19 branch. I will push this branch to xen tip tree after I
have tested it. Unfortunately my test environment is completely broken
right now so I will need to come up with something in the meantime.
Hopefully in the next couple of days.
Note that I won't be testing the new interfaces.
