Mostly because psi is so intertwined with the scheduler that it's been
maintained through the scheduler tree. But let's add an entry for it,
the sched/ directory matching will ensure it shows all pertinent CCs:
$ ./scripts/get_maintainer.pl kernel/sched/psi.c
Johannes Weiner <hannes@xxxxxxxxxxx> (maintainer:PRESSURE STALL INFORMATION (PSI))
Ingo Molnar <mingo@xxxxxxxxxx> (maintainer:SCHEDULER)
Peter Zijlstra <peterz@xxxxxxxxxxxxx> (maintainer:SCHEDULER)
Juri Lelli <juri.lelli@xxxxxxxxxx> (maintainer:SCHEDULER)
Vincent Guittot <vincent.guittot@xxxxxxxxxx> (maintainer:SCHEDULER)
Dietmar Eggemann <dietmar.eggemann@xxxxxxx> (reviewer:SCHEDULER)
