From: Paul E. McKenney
Date: Wed Sep 22 2010 - 20:50:44 EST


Hello!

This patchset contains fixes for problems identified in -next testing
and some statistics and documentation updates. The patches are as follows:

1. Update stallwarn.txt to include stall warnings caused by
real-time processes (yes, even in mainline kernels).
2. Fix some performance bugs in TINY_PREEMPT_RCU.
3. Fix an overactive rcu_bootup_announce_oddness() warning.
4. Eliminate a redundant #ifdef (from Christian Dietrich).
5. Fix the new sparse-aware primitives to correctly handle
macro arguments with side effects.
6. Fix some issues sparse found in rcutorture.c.
7. Add some tracing data to help compute estimates of how long
RCU callbacks are queued.
8. Fix up the Kconfig message for PROVE_RCU_REPEATEDLY.

For a testing-only version of this patchset from git, please see:

Thanx, Paul
