Couple questions out of this:
1. Does anyone care enough to produce a patch for vmware's module?
2. What does this change accomplish for reiser4?

I'd say that namesys is using UML (user-mode-linux.sf.net) to develop raiser4 (smart guys, uml rocks).

These are probably left overs from UML's SKAS-host patch. If I'm correct you may try to reverse the SKAS patch from that tree (the patch is located at UML's site). It won't do any harm, anyway...
