From 9aaffc898ff4a3df18c5fc4b9e0fa47e779ad726 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 23 May 2007 13:57:41 -0700 Subject: 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.
