i've uploaded -J7:

   http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.8-rc2-J7

Changes since -J4:

- fix the latency that occurs when a large number of files are deleted: 
  the guilty one is select_parent() - this should fix the Bonnie latency 
  reported by Lee Revell.

[ the ones below add conditional reschedule points that dont affect 
  users who have kernel_preemption turned on:]

- fix /proc/PID/maps latencies

- fix latencies triggered by 'df' on a large filesystem

- fix exec() latency when dealing with large environments

- add might_sleep() to lock_buffer()
