Hi,
mbind(start, len, ...) currently requires that "start" be page-aligned, but not "len" (which automatically gets page-rounded up). This is a bit odd:
- the userland type of start is void*, which people would expect to be a pointer to some variable. - start needing to be page-aligned but len not needing to is not very consistent. - none of this is documented in the manual page dated 2006-02-07
So one of those should probably be done to free people from headaches:
- document "start" requirement in the manual page - require len to be aligned too, and document the requirements in the manual page - drop the "start" requirement and just round down the page + adjust size automatically.
