I'm faced with porting some code that has patched the 8.0 kernel to accept up to 16 args in a syscall. It makes my skin crawl a bit but if I can't give a good reason to suggest that they do things differently in 10 (pass a pointer to a struct maybe) then I'll just take the easy path and s/8/16/ in the appropriate line in amd64/include/proc.h and get on with life. I initially thought it may confuse things like ktrace or truss but I haven't seen any problems.. allocating more space on the stack is another thing but you only ever do one syscall at a time. Julian
