Hi Omar,

Two changes here:

- block/006 wants to use the iops results, but it isn't using _fio_perf.
- Add block/010 to test for shared vs non-shared tags performance.

Thanks, Jens, applied the first one, but

[ 1876.142470] null_blk: unknown parameter 'shared_tags' ignored

Am I missing a patch?

Yes, the shared tags is a new feature, it's coming in 4.13. But I checked
and it doesn't abort the module load. So the test ends up just being the
same thing run twice, if shared_tags isn't available. I figured that
was good enough.

Sounds good, I'll apply it as-is and add an extra patch on top that
checks if the module parameter exists.
