rcu: Clean up the warning message about RCU not defined
When the kernel is built, there is some message printed as
following:
include/linux/rcupdate.h:80:7: \
warning: "CONFIG_TINY_RCU" is not defined
So I did "grep _RCU .config" to search the information of "CONFIG_TINY_RCU"
in .config file and the result is listed as following:
Command:
grep _RCU .config
Result:
CONFIG_TREE_RCU=y
# CONFIG_TREE_PREEMPT_RCU is not set
# CONFIG_TINY_RCU is not set
CONFIG_RCU_TRACE=y
CONFIG_RCU_FANOUT=64
# CONFIG_RCU_FANOUT_EXACT is not set
CONFIG_TREE_RCU_TRACE=y
# CONFIG_RCU_TORTURE_TEST is not set
# CONFIG_RCU_CPU_STALL_DETECTOR is not set
Though the "WARNING" does not give impact to build kernel, I think
it should be cleaned up. And I made the patch for modifying it.
With this patch there is not any other warning message of
CONFIG_TINY_RCU and the kernel could be built successfully. And I
confirmed that the built kernel works well.
