Subject: [PATCH 0/5] rv: LTL per-cpu monitor type and real-time scheduling monitor

Hi,

This series adds support for linear temporal logic per-cpu monitor type,
analogous to deterministic automaton per-cpu monitor. Then a new per-cpu
monitor is added which validates real-time scheduling.

Nam Cao (5):
  rv/ltl: Prepare for other monitor types
  rv/ltl: Support per-cpu monitors
  verification/rvgen/ltl: Support per-cpu monitor generation
  sched: Add rt task enqueue/dequeue trace points
  rv: Add rts monitor
