I run SRP test on Fedora 27, and not run any LIO specific commands
to load it, seems it is done automatically.

So looks it might not a good idea to fail SRP test if LIO is loaded,
just wondering why your SRP test can't make the two co-exist?

The LIO configuration is system-wide. Only one configuration can be
loaded at any given time. I don't think that the SRP tests should wipe
any existing LIO configuration data if e.g. blktests is run accidentally
on a production server. I think that wiping LIO configuration data should
be a manual step.

I think this should be handled in requires(). I.e. check if LIO is
already configured and then skip the test if it is.

As far as I know the requires() function is per test and there is no 
such function at the group level. I prefer to define this test once at 
the group level instead of copy/pasting the same test thirteen times in 
each test.
