Andrew Morton [interview] released 2.6.0-test9-mm2 noting, "Various random fixes. Maybe about half of these are 2.6.0-worthy." Regarding recently reported issues with I/O [story], Andrew noted that -mm2 includes "some improvements to the anticipatory IO scheduler and more readahead tweaks should help some of those database benchmarks." He concludes, "The anticipatory scheduler is still a bit behind the deadline scheduler in these random seeky loads - it most likely always will be."

Also included in this release is forcedeth, "A new driver for the ethernet interface of the NVIDIA nForce chipset, licensed under GPL." Find more information about Andrew's -mm tree here. Read on for the full changelog of -test9-mm2.

- Various random fixes.  Maybe about half of these are 2.6.0-worthy.

- Some improvements to the anticipatory IO scheduler and more readahead
  tweaks should help some of those database benchmarks.

  The anticipatory scheduler is still a bit behind the deadline scheduler
  in these random seeky loads - it most likely always will be.

- "A new driver for the ethernet interface of the NVIDIA nForce chipset,
  licensed under GPL."

  Testing of this would be appreciated.  Send any reports to linux-kernel
  or [email blocked] and Manfred will scoop them up, thanks.


- I shall be offline for a couple of days.
