Whoops, make that:
fsidHash = fsid * 67289 % totalSectorsOnAllInodeZones;
virtualSector = fsidHash * 2;
for(i = 0; ; i++) {
if(zone[i].type == INODE_ZONE) {
if(zone[i].sectors <= virtualSector) {
virtualSector -= zone[i].sectors;
} else {
break;
}
}
sector = virtualSector + zone[i].start;
partition = i;
Well, close enough for pseudo-code anyway...
