Yes. And rip out all that code related to setting up the slabs. I plan
to add WARN_ONs to bio_add_page and friends to detect

How about getting rid of the slabs there and use kmalloc? Kmalloc in mm
(and therfore hopefully 2.6.24) will convert kmallocs > PAGE_SIZE to page

Yes.
How about getting rid of the slabs there and use kmalloc? Kmalloc in mm

Yes. And rip out all that code related to setting up the slabs. I plan
