Re: [Xen-devel] Re: [PATCH 2.6.12.6-xen] sysfs attributes for xen

In the final version, there will be available Xen headers, and the patch

Good question, I need some advice. The Xen hcall headers get soft-linked into
every paravirtualized OS tree: linux, bsd, solaris, etc. In linux right now the
xen version.h shows up as /include/asm-xen/version.h.
This file uses typedefs for every important parameter. For example, typedef char [1024] xen_capabilities_info_t;.
But as Greg says TYPEDEFS ARE EVIL.
Last resort would be to use the funky gcc #include_next to override the xen hcall headers with a linux-specific hcall headers. But I don't know if that would be cool with lkml either.
So, advice would be welcome :).
thanks,
Mike
