I'm still waiting for the next version of the indirect punch patches
(which you said you'd work on after the extent status patches, given
that I had noted other xfstest failures that were apparently caused by
these patches), but in the mean time, adding a tracepoint for
ext4_punch_hole() seem like it would make sense, so I've applied this
patch to the ext4 tree.
