| |
Hello!
This patch series provides further updates to RCU's interaction with CPU hotplug. The individual patches are as follows:
1. Fix an obsolete comment describing ->onofflock. 2. Make rcutorture print the errno from cpu_down() failure if the "verbose" module parameter is specified. 3. Make _cpu_down() use stop_cpus() instead of __stop_machine(). 4. Rename ->onofflock to ->orphan_lock to correctly indicate this lock's current scope. 5. Avoid counter wrap in synchronize_sched_expedited(). 6. Move synchronize_sched_expedited() from global variables to the rcu_state structure. 7. Instrument synchronize_rcu_expedited() for debugfs tracing.
Thanx, Paul
