You need a commit message that describes the test....

Ok, we've now got 4 or 5 copies of this same set of tests for
different fallocate commands. Please factor.

Really?

Oh, it's a direct copy-n-paste of the XFS_IOC_ZERO_RANGE test with
s/zero/fzero/.

Please factor along the same lines as _generic_test_punch so we
don't have duplicated code in the tests.

Also, I haven't seen patches 3, 4 or 6 on the list, and they haven't
made it to the archive, either. Can you please resend them?

Cheers,

Dave.
