This document gives a brief rationale for the TINY_RCU test cases.
Kconfig Parameters:
CONFIG_DEBUG_LOCK_ALLOC -- Do all three and none of the three.
CONFIG_PREEMPT_COUNT
CONFIG_RCU_TRACE
The theory here is that randconfig testing will hit the other six possible
combinations of these parameters.
Kconfig Parameters Ignored:
CONFIG_DEBUG_OBJECTS_RCU_HEAD
CONFIG_PROVE_RCU
In common code tested by TREE_RCU test cases.
CONFIG_NO_HZ_FULL_SYSIDLE
CONFIG_RCU_NOCB_CPU
CONFIG_RCU_USER_QS
Meaningless for TINY_RCU.
CONFIG_RCU_STALL_COMMON
CONFIG_RCU_TORTURE_TEST
Redundant with CONFIG_RCU_TRACE.
CONFIG_HOTPLUG_CPU
CONFIG_PREEMPT
CONFIG_PREEMPT_RCU
CONFIG_SMP
CONFIG_TINY_RCU
CONFIG_TREE_PREEMPT_RCU
CONFIG_TREE_RCU
All forced by CONFIG_TINY_RCU.
