New Revision: 262466
URL: http://svnweb.freebsd.org/changeset/base/262466

Log:
  Make all 8 syscall arguments available to syscall probes in the same way
  that this is done for SDT probes. This fixes the syscall/tst.args.d test,
  which was failing because mmap(2)'s sixth argument wasn't available to the
  probe.
