Better as __raw_readsb() yes? Or maybe ioread8_rep().
... speaking of which, maybe the MTD layer can finally
default to using the accelerated block PIO calls, now
that ioreadX_rep() is supposed to work on all arches...
Last time I measured, that change alone was worth
something like a 10% speedup. Maybe more.
