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_RCU_NOCB_CPU 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_PREEMPT_RCU CONFIG_TREE_RCU All forced by CONFIG_TINY_RCU.
