Subject2.5.60-mm2

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.60/2.5.60-mm2/

. Robert has fixed up Ingo's scheduler update, so that's back in.

. Considerable poking at the NFS MAP_SHARED OOM lockup. It is limping
along now, but writeout bandwidth is poor and it is still struggling.
Needs work.

. There's a one-liner which removes an O(n^2) search in the NFS writeback
path. It increases writeout bandwidth by 4x and decreases CPU load from
100% to 3%. Needs work.

. A patch to permit direct-io reads of the partial block at EOF. Seems to
work, but needs more testing.

. There is another anticipatory scheduler patch over in experimental/.

The main obective of the anticipatory scheduler is not really to improve
interactivity. It is to increase throughput. Nick is showing some
impressive benchmark results with this now. Some benchmarking of the
non-contest variety would be appreciated.

. Added Matthew Jacob's Qlogic ISP driver for a bit of testing. It locks
up mysteriously with my ISP12160 controller. Testing results for other
controllers would be appreciated.
