i'm pleased to announce release -v17 of the CFS scheduler patchset.

The rolled-up CFS patch against v2.6.22-rc4, v2.6.22-rc4-mm2, v2.6.21.5
or v2.6.20.13 can be downloaded from the usual place:


-v17 includes a bigger change: the CFS-core changes in preparation of
the group-scheduling feature, written Srivatsa Vaddagiri. Dmitry
Adamushko provided cleanups and further generalizations to this code and
the modularization of CFS has been further enhanced as a result. To
users, these changes are mostly invisible.

Changes since -v16:

- lots of core updates to support group scheduling, and related
cleanups. (Srivatsa Vaddagiri, Dmitry Adamushko)

- tuned the runtime-limit up a bit, based on relentless testing done by
Tobias Gerschner.

- the new, precise load-calculation method for SMP balancing has been
further enhanced, and is now active by default. (Dmitry Adamushko)

- fix SCHED_IDLEPRIO support (based on feedback from Thomas Sattler)

- further updates to /proc/sched_debug and /proc/PID/sched

- more cleanups

As usual, any sort of feedback, bugreport, fix and suggestion is more
than welcome!
