The same comment for this as for [04/18], there are two many overrides 
which are not necessary because you can replace "mv $TEST_IMG 
$TEST_IMG.orig" with "TEST_IMG=$TEST_IMG.orig _make_test_img 8G" without 
touching other parts.

Especially here, overriding TEST_IMG inside a utility function is not right.

The problem is, that in its original form io_test2 only works with protocol file. Maybe its better to split io_test2 into
2 parts.

I haven't looked at the full series yet, but yes, probably all the other
functions in common.pattern as well.

In general, I think the primary test image should be $TEST_IMG, not
$TEST_IMG.orig. Hiding the creation of a copy in common.pattern, after
which $TEST_IMG becomes valid, doesn't make it easier to understand
either.

Maybe thats a little overkill just testing the NFS driver works. Its a rework of almost the whole test suite.

If you agree I would send an update with v6 of the NFS driver that just includes patch 1,2,3,16,17 of this series.
This enables for basic testing of the driver. The indepth tests for the formats should trigger a bug on any protocol
and I think its ok to test this with file.
