ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test9/2.6.0-test9-mm1

• kernel.org is being slow – the diff is also at

http://www.zip.com.au/~akpm/linux/patches/2.6.0-test9-mm1.gz

• A couple of fixes for VM memory reclaim.
• The ia32 EFI code seems to be complete now.
• The recent IO scheduler regressions should be fixed.
• Dropped the runtime-selectable-IO-scheduler patches.
• A number of fixes to the pagecache readahead code should help
  seeky workloads such as non-direct-io databases.
• Various fixes, mostly minor.

Changes since 2.6.0-test8-mm1:
