Subject: xfstests generic/285 fails reliably on Trond's linux-next branch

Now that 207 is fixed the next test starts failing.. 285 is
the SEEK_HOLE/DATA sanity check, which might help with figuring out
which of the recent changes introduced it.

A week later this still fails with the linux-next branch. Plain NFSv4.2
against a Linux/XFS server. The 285.full file documenting the failures
is attached below:

What mount options are you using? The test passes for me on xfs, btrfs, and ext4.

Thanks,

No mount options at all - just forcing 4.2 with a small patch to
super.c.

I've tried to bisect the issue, but I now see it with Linux 4.7-rc2 as
well. I did upgrade xfstests in the meantime, so I'll see if that
caused the issue, or if it's something that's new in Linux 4.7-rc2 and
Tronds earlier tree was using an older baseline.
