Subject[PATCH tip/core/rcu 0/9] Preview of additional RCU changes for 3.3
Hello!

This patchset is in addition to the set previously posted (see
https://lkml.org/lkml/2011/11/2/363). This new set permits the
reworked RCU_FAST_NO_HZ code to be used from TREE_PREEMPT_RCU,
allows rcutorture to shut down the system after a fixed time
period (useful for KVM-based testing), adds an API to
replace the "->pid == 0" discussed in response to the earlier
patch set, and applies this API where applicable. The patches are
as follows:

1. Update the RCU_FAST_NO_HZ config definition to allow it to
be used in TREE_PREEMPT_RCU builds, since that is now legal.
2. Add a module parameter that permit rcutorture to shut down the
system cleanly after the test has run for the specified time.
3. Add a module parameter to allow rcutorture start running
as soon as it is initialized.
4. Add is_idle_task() API to replace open-coded tests of ->pid
against zero.
5-9. Apply the new is_idle_task() API where it makes sense.

For a testing-only version of this patchset from git, please see the
following subject-to-rebase branch:

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/dev

Thanx, Paul
