New Revision: 269724
URL: http://svnweb.freebsd.org/changeset/base/269724

Log:
  MFC r265631:
  Re-apply r248644. This fixes an annoying problem which caused dtrace -c to
  fail to attach to stripped binaries. With the _r_debug_postinit symbol,
  dtrace(1) can now set a breakpoint in the victim process after it has
  registered its DOF table(s) with the kernel. r_debug_state cannot be used
  for this purpose since it is called before DOF is made available, in which
  case dtrace(1) cannot create USDT probes before the program begins
  execution.
