and when CONFIG_PROC_FS is not set/enabled, kernel/sched/psi.c gets:

../kernel/sched/psi.c: In function ‘psi_proc_init’:
../kernel/sched/psi.c:1287:56: error: macro "proc_create" requires 4 arguments, but only 3 given
   proc_create("pressure/cpu", 0, NULL &psi_cpu_proc_ops);
                                                        ^
../kernel/sched/psi.c:1287:3: error: ‘proc_create’ undeclared (first use in this function); did you mean ‘sock_create’?
   proc_create("pressure/cpu", 0, NULL &psi_cpu_proc_ops);
   ^~~~~~~~~~~
   sock_create
