EXT4, Btrfs, XFS & F2FS On Linux 4.6 Through 4.9

With the SQLite test the only interesting result is with Btrfs where from Linux 4.7 to 4.8 there is a nice performance improvement that is still maintained with Linux 4.9. The three other file-systems saw no real performance change.

With FIO random read the performance was unchanged but for random writes XFS / EXT4 / F2FS saw a performance bump with Linux 4.8 that wasn't carried over to Linux 4.9. Btrfs here, meanwhile, was unchanged and much slower than the other three.

But FIO's sequential read test is basically the opposite of the random read results.

Linux 4.8 remained an outlier for the sequential write results, but at least this regression seems to be addressed by 4.9.
