Roland, The intention is to keep things simple. In case it was not apparent from my submission, the intention of the inlines is to pre-fetch single cache lines. Also, neither SPARC nor x86 have single prefetch instructions to fetch multiple cache lines so a length argument would be extraneous at this point. Remember that these interface are intended to be undocumented and unstable so any future changes that aid performance would be welcome.
