Revert "prohibit rcutorture from being compiled into the kernel" (1462a200) · Commits · 戴 / test

This reverts commit . That commit was a very bad idea. RCU_TORTURE found many boot timing bugs and other sorts of bugs in the past, so excluding it from boot images is very silly. The option already depends on DEBUG_KERNEL and is disabled by default. Even when it runs, the test threads are reniced. If it annoys people we could add a runtime sysctl.

		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.
