prohibit rcutorture from being compiled into the kernel
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. Signed-off-by: Paul E.

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.
