Subject: prohibit rcutorture from being compiled into the kernel
From: "Paul E. McKenney" <paulmck@xxxxxxxxxxxxxxxxxx>
There have been a number of instances where people have accidentally compiled
rcutorture into the kernel (CONFIG_RCU_TORTURE_TEST=y), which has never been
useful, and has often resulted in great frustration. The attached patch
prohibits rcutorture from being compiled into the kernel. It may be excluded
altogether or compiled as a module. People wishing to have rcutorture hammer
their machine immediately upon boot are free to hand-edit lib/Kconfig.debug to
remove the "depends on m" line.
Thanks to Randy Dunlap for the trick that makes this work.

This option provides a kernel module that runs torture tests
on the RCU infrastructure. The kernel module may be built
after the fact on the running kernel to be tested, if desired.
- Say Y here if you want RCU torture tests to start automatically
- at boot time (you probably don't).
Say M if you want the RCU torture tests to build as a module.
Say N if you are unsure.
