According to description of NFS and directIO in open(2), especially
"The Linux NFS client places no alignment restrictions on
O_DIRECT I/O", ignore some FAILs in diotest4.
According to nfs(5), NLM supports advisory file locks only. So skip
fcntl16 test if NFS.

You are modifying runtest_f() which is invoked in multiple test scenarios.
I suppose that not all the test cases should be excluded from the
execution on NFS. For example, "negative fd".
I think we should disable only ones which don't work with NFS.

Hmm. diotest4.c has many duplicated parts of code like 'open(O_DIRECT)'
and tests like 'if (l_fail)' and 'if (ret != 0)'.
What do you think about cleaning these things up before doing functional
changes? :)
Thanks.
