rGfd404e957dd9: racct: Fix accounting of CPU time for the system idle process
rG33be1632047c: racct: Fix accounting of CPU time for the system idle process
Summary
  • Add a flag which cleanly indicates that a given process is the system idle process.
  • Modify racctd() to skip over the idle proc when aggregating CPU time and other metrics which don't apply to the idle thread.
  • Remove handling for idle threads from racct_getpcpu().
