Patches for > util_linux might also be handy. There were 5 xfstests patches posted that used the _test_generic_punch infrastructure to test this functionality. See the december 08 index here, search for "shared/00[1-5]": http://oss.sgi.com/archives/xfs/2013-12/index.html They need a little rework, but otherwise the test code is there. Having the feature added to fsx and fsstress would probably be a good idea, though.
