Also included are some minor fixes and improvements. This series is based on the original work done by Jonas Rabenstein which was submitted in March 2018.[1] I tried to apply suggestions made in review on the list and do some further improvements. The most contentions issue in the original series was the IOCTL for shadow MBR write but I think no better approach was found[2] so this was not changed. I'm open to suggestions. There is a fork of sed-opal-temp that can use these new IOCTLs.[3] I tested these on Samsung 840 EVO and 850 EVO drives, on x86-64 and arm64 systems. The series applies on v5.0-rc2.
