Mmm... I got the following error when I try to compile the patch on latest kernel tip:

kernel/sched/fair.c:3263:3: error: implicit declaration of function âstatic_branch_LB_MINâ [-Werror=implicit-function-declaration]
kernel/sched/fair.c:3263:46: error: â__SCHED_FEAT_LB_MINâ undeclared (first use in this function)
kernel/sched/fair.c:3263:46: note: each undeclared identifier is reported only once for each function it appears in
cc1: some warnings being treated as errors
make[2]: *** [kernel/sched/fair.o] Error 1
make[1]: *** [kernel/sched] Error 2
make: *** [kernel] Error 2
