Cover letter [PATCH tip/core/rcu 0/13] Torture-test updates for 4.2
Hello!
This series contains torture-test updates:
1. Use correct locking primitive, thus avoiding deadlock, courtesy
of Alexey Kodanev.
2. Exchange TREE03 and TREE04 geometries in order to improve bug-location
rates.
3. Exchange TREE03 and TREE08 NR_CPUS, speed up CPU hotplug to further
improve bug-location rates.
4. Allow negative values of nreaders to in order to oversubscribe
the CPUs, again to improve bug-location rates.
5. Change longdelay_us to longdelay_ms in order to better reflect
reality. (Not that gcc cares, but people reading the code just might.)
6. Replace open-coded memory barriers with the shiny new
smp_store_release() and smp_load_acquire() primitives.
7. Test SRCU cleanup code path in order to improve test coverage.
8. Avoid explicitly setting CONFIG_TASKS_RCU, given that it is
now set implicitly based on other configuration options.
9. Update configuration fragments from CONFIG_RCU_FANOUT_EXACT to
the new rcutree.rcu_fanout_exact= boot parameter.
10. Make rcutorture scripts force RCU_EXPERT so that they can still
build the needed kernel configurations.
11. Update TREE_RCU-kconfig.txt to describe new kernel-parameter
setup.
12. Make torture scripts display "make oldconfig" errors
13. Allow repetition factors in Kconfig-fragment lists. Because
typing 48 repetitions of "TINY02" is getting old.
Thanx, Paul
