    sys/kern             subr_sleepqueue.c subr_turnstile.c 
  Log:
  Add two new kernel options to allow rudimentary profiling of the internal
  hash tables used in the sleep queue and turnstile code.  Each option adds
  a sysctl tree under debug containing the maximum depth of any bucket in
  the hash table as well as a separate node for each bucket (or chain)
  containing the current depth and maximum depth for that bucket.
