    skip instrumentation attempts on anonymous mmap() · 7bad56a3
    Philip Carns authored
    Anonymous mmap() calls have no backing file and therefore won't match
    any Darshan characterization records, so we can skip the record lookup
    in this case.  This also fixes a deadlock on Cray systems with hugepages
    enabled, see #210.
