Hello!
This patchset shows additional patches queued for 2.6.37, over
and above those posted at http://lkml.org/lkml/2010/7/14/334 and
at http://lkml.org/lkml/2010/8/9/332. These are all trivial fixes.
The patches are as follows:
1. Allow kernel debuggers to avoid spurious RCU CPU stall warnings
when restarting from a breakpoint via a new rcu_cpu_stall_reset().
2. Repair code-duplication FIXMEs. This code was temporarily
duplicated to avoid inter-patch dependencies in the RCU tree.
3. Document some additional ways of stalling updates to prevent
call_rcu()-induced OOM situations.
4. Update srcu_read_lock() docbook comment to note that it is
illegal to wait for a given flavor of SRCU grace period while
in that same flavor of SRCU read-side critical section.
5. Combine duplicate code, courtesy of a newly refurbished
CONFIG_PREEMPT_RCU symbol. Also convert from macro to
static inline function in a couple of places.
6. Apply the TINY_PREEMPT_RCU read-side speedups/fixes to
TREE_PREEMPT_RCU. This update to TINY_PREEMPT_RCU update was
posted at http://lkml.org/lkml/2010/8/17/437.
7. Add a comment stating that list_empty() serves the function of
the non-existent list_empty_rcu().
