Matt was tooling around with filebench and found that it was using mmap. We should
investigate to see whether this is necessary or not.
Talked to rmc and one discussed was mmap and filebench. As we thought, we're just
mmap'ing files so we can easily flush them (MS_INVALIDATE / see fileset_freemem() )
after we've created all the files and are ready to do the real run.
We can ditch mmap and just put the file system caching in the fs_flush script
(that is, unmount/ remount). This is much like what we do for ZFS today (export /import
the pool).
