Hiya,

If you're going to add new BIOs, can I possibly request we add a
"BIO_WRITE" variant for NOR flash, that can be interpreted as "don't
do a read-modify-write, but simply write over whatever the underlying
storage device has" ?

That way NOR flash filesystems can do incremental writes of pages
without having to do a read/erase/modify/write pass, where the erase
is very very expensive.

Thanks,


Adrian
