DO NOT pick it to stable tree.
(Since the title has "fix", this statement may help stop
AI pick it to stable tree)
The tokens SRCU and TINY_RCU are not defined by any configurations,
they should be CONFIG_SRCU and CONFIG_TINY_RCU. But there is no
harm when "TINY_RCU" is wrongly used, which are always non-defined,
which makes "!defined(TINY_RCU)" always true, which means
the code block is always inclued, and the included code block
doesn't cause any compilation error so far when CONFIG_TINY_RCU.
It is also the reason this change doesn't need for stable.
