queue_pull_task() is not defined for CONFIG_SMP=n case, following build error
is seen while building the kernel with SMP=n:
CC kernel/sched/deadline.o
kernel/sched/deadline.c: In function âswitched_from_dlâ:
kernel/sched/deadline.c:1713:2: error: implicit declaration of function
âqueue_pull_taskâ [-Werror=implicit-function-declaration]
queue_pull_task(rq);
^
cc1: some warnings being treated as errors
Thanks,
Kamalesh.
