Subject: [PATCH 00/14] sched: SCHED_DEADLINE v9

Hello everyone,

SCHED_DEADLINE patchset v9, less than a month after last version [1]!

Changes w.r.t. v8:

 - rebase on top of 3.12;
 - all comments from Peter Zijlstra and Ingo Molnar applied (thanks!):
    + auxiliary functions for UP/SMP cases
    + add a smp_rmb to match dl_set_overload smp_wmb
    + different clocks for deadlines and runtime need further study
    + amend the comment about yield_task_dl semantic
    + use an accessor to read the rq clock
    + clarify 06/14 changelog (why we want to specify periods != deadlines)

The development is taking place at:
   https://github.com/jlelli/sched-deadline

branch: sched-dl-V9-rebase (this patchset on top of tip/master).

Check the repositories frequently if you're interested, and feel free to
e-mail me for any issue you run into.

Test applications:
  https://github.com/gbagnoli/rt-app 
  https://github.com/jlelli/schedtool-dl

Development mailing list: linux-dl; you can subscribe from here:
http://feanor.sssup.it/mailman/listinfo/linux-dl
or via e-mail (send a message to linux-dl-request@...is.sssup.it with
just the word `help' as subject or in the body to receive info).

The code was being jointly developed by ReTiS Lab (http://retis.sssup.it)
and Evidence S.r.l (http://www.evidence.eu.com) in the context of the ACTORS
EU-funded project (http://www.actors-project.eu) and the S(o)OS EU-funded
project (http://www.soos-project.eu/). Development is now supported by the
JUNIPER EU-funded project [2].

As usual, any kind of feedback is welcome and appreciated.

Thanks in advice and regards,

 - Juri
