Unless you've spammed the commits I made to umass.c they've been in the tree
for a month or so. :-P Look at the UFI transform for example:
umass_ufi_transform(struct umass_softc *sc, unsigned char *cmd, int cmdlen,
unsigned char **rcmd, int *rcmdlen)
{
...
if (umass_scsi_6_to_10(cmd, cmdlen, rcmd, rcmdlen))
return (1);
...
}
Same code is in the atapi_transform function as well. Just add those two lines
before the big switch() on the command to the scsi_transform function.
