[comp.os.minix] Floppy caching worries me

I am trying to modify Minix floppy device driver (Minix 1.2) in order to
improve its efficiency by implementing TRACK AT A TIME CACHING.

If someone in the Minix World has already done this or something related
to the subject, it would be nice if he could give some advice or more...

I have such plans, too...
But I advise you to go to MINIX 1.5 first,
the most easiest approach (no FS changes) seems to switch track buffering
on at the beginning of on I/O-Request VECTOR and clean the buffers up
at the end of this vector.
