Hi Andrew,

Stupid question: Would you accept a patch that extends
get_user_pages() to accept an additional "struct scatterlist vector[]"?
Because otherwise we have a senseless pages[] array in memory,
which we copy then into a scatterlist.
A different function using most of get_user_pages() is also
possible.
And last but not least: EXPORT_SYMBOL_GPL() of both, to make it
usable in modules.
Rationale: Most users of get_user_pages() and kiobufs really want
a struct scatterlist sooner or later to transmit it via DMA.
PIO-Users would need a copy_from_user_to_io() and the
counterpart. ALSA implements it somewhere.
So while we are at it... ;-)

Ingo Oeser
