However, it does explore some obscure parts of the API. For example, the elimination of user.h makes it impossible to use PTRACE_SETFP[X]REGS, as there is no way to tell what size buffer should be passed in. I'm all for minimizing the headers exported to userspace (and have made a small contribution in that direction - ptrace-abi.h). I'm happy to make UML stop using things it shouldn't. At the same time, it should be possible to use the full userspace API.
