This patch series extends SED OPAL support: it adds IOCTL for setting the shadow

IOCTL for writing to the shadow MBR. Also included are some minor fixes and
improvements.
Actually most of it is really useful cleanups and small fixes for the
existing OPAL code. Any chance you could resend just those bits as
a first series ASAP? I'll try to spend some time to to review the
actual feature additions in the meantime.
There is a fork of sed-opal-temp that can use these new IOCTLs.[2] I tested
these on Samsung 840 EVO and 850 EVO drives, on x86-64 and arm64 systems.
Which brings up another question: how do we get a properly maintained
version of the sed-opal tool up ASAP? It's been a bit bitrotting
unfortunately, and the documentation and error handling hasn't been all
that great to start with. Are we going to find a good home for it?
Util-linux for example?
