+ suffix is used with a sequential IO pattern, then the value
specified will be added to the generated offset for each IO.
For instance, using rw=write:4k will skip 4k for every
write. It turns sequential IO into sequential IO with holes.
create_on_open=bool Don't pre-setup the files for IO, just create open()
when it's time to do IO to that file.

pre_read=bool If this is given, files will be pre-read into memory before
starting the given IO operation. This will also clear
the 'invalidate' flag, since it is pointless to pre-read
file. Can be used to store data of the bandwidth of the
jobs in their lifetime. The included fio_generate_plots
