-directory=str Prefix filenames with this directory. Used to places files
+directory=str Prefix filenames with this directory. Used to place files
in a different location than "./".
filename=str Fio normally makes up a filename based on the job name,
opendir=str Tell fio to recursively add any file it can find in this
directory and down the file system tree.
-lockfile=str Fio defaults to not doing any locking files before it does
+lockfile=str Fio defaults to not locking any files before it does
IO to them. If a file or file descriptor is shared, fio
can serialize IO to that file to make the end result
consistent. This is usual for emulating real workloads that
size=int The total size of file io for this job. Fio will run until
this many bytes has been transferred, unless runtime is
limited by other options (such as 'runtime', for instance).
- Unless specific nr_files and filesize options are given,
+ Unless specific nrfiles and filesize options are given,
fio will divide this size between the available files
specified by the job.
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
+ and then drop the cache.

unlink=bool Unlink the job files when done. Not the default, as repeated
runs of that job would then waste time recreating the file
set again and again.

disk_util=bool Generate disk utilization statistics, if the platform
supports it. Defaults to on.

C Thread created.
I Thread initialized, waiting.
