Michael> How does this look? Is this the intended usage? Looks OK, although I would like to see test results too. However I wonder what get_user_pages() does with a huge page region -- does it give back huge pages or does it waste a lot of effort creating 4KB pages to cover the region?
Also, this > + u32 mask = 0; and this > + mem->page_size = ffs(mask) ? 1 << (ffs(mask) - 1) : (1 << 31); makes me think that maybe we should change mem->page_size to an unsigned long, since it's quite possible that a memory region spans more than 2GB physically contiguous (especially if support for GB pages on amd64 is added). - R. _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
