The patch is blk-13C, before integration in 2.4.0-acX it
was renamed to blk-14 because I added some low mem hysterisis.
*.kernel.org/pub/linux/kernel/people/axboe/patches/2.4.0-ac4/blk-13C.bz2
is the latest non-integrated patch.

Yes, Linus integrated blk-13C in 2.4.1-pre5, and pre6 went to blk-14.
So the patch is in the main tree now.
