Which means that these changes are likely to become an issue not just for Gentoo users in the future. > This makes it very > hard for things like UML, that are heavily tied to the kernel, to build. > As Jeff pointed out, this is part of the userspace api: "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." Can you suggest a way to code around this issue or is this going to require an update to the Gentoo kernel headers? Let me know if I can help.
