  # HEAD: 0d3a00b370424f5f1b9fd037bc8a4a3e7cbf0939: smp: Reduce NMI traffic from CSD waiters to CSD destination (2023-07-10 14:19:04 -0700)

----------------------------------------------------------------
CSD lock commits for v6.5

This series reduces the number of stack traces dumped during CSD-lock
debugging.  This helps to avoid console overrun on systems with large
numbers of CPUs.

----------------------------------------------------------------

      smp: Reduce logging due to dump_stack of CSD waiters
      smp: Reduce NMI traffic from CSD waiters to CSD destination
