    sys/kern             kern_ktrace.c 
  Log:
  SVN rev 219041 on 2011-02-25 22:03:28Z by dchagin
  
  ktrace_resize_pool() locking slightly reworked:
  1) do not take a lock around the single atomic operation.
  2) do not lose the invariant of lock by dropping/acquiring
     ktrace_mtx around free() or malloc().
  
  MFC after:      1 Month.
