If TORTURE_TEST=y(selected by TORTURE_LOCK_TEST) and RCU_TORTURE_TEST=n, the following error is seen while building kernel/torture.c
kernel/torture.c: In function torture_onoff: kernel/torture.c:239:3: error: implicit declaration of function rcutorture_sched_setaffinity; did you mean __NR_ia32_sched_setaffinity? [-Werror=implicit-function-declaration] rcutorture_sched_setaffinity(current->pid, cpumask_of(0));
Using sched_setaffnity() instead of rcutorture_sched_setaffinity() to avoid the error.
