bw_mmap_rd creates a memory mapping to the file and then reads the mapping in an unrolled loop similar to
       that  used  in bw_mem_rd(8).  The benchmark is intended to be used on a file that is in memory, i.e., the
       benchmark is a reread benchmark.  Other file benchmarking can be done with lmdd(8).

       The size specification may end with ``k'' or ``m'' to mean kilobytes (* 1024)  or  megabytes  (*  1024  *
       1024).

       This benchmark should move approximately the reported amount of memory.
