Someone (aka Tospin, infinicon, and Amasso) should probably post a patch adding '#define VM_REGISTERD 0x01000000', and some extensions to something like 'madvise' to set pages to be registered. My preference is said patch will also allow a way for the kernel to reclaim registered memory from an application under memory pressure. _______________________________________________ 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
