It is. It looks like this code is different in tls-maxphys and HEAD. I wonder if we really want to read in power-of-2 chunks here, or just multiple of page size. Reading the code which calls ra_startio(), I'm not sure why size of chunksize would be a power-of-2. -- Manuel Bouyer <bou...@antioche.eu.org> NetBSD: 26 ans d'experience feront toujours la difference --
