I read the patch and linked issues. It looks like an OpenZFS bug to me, which wasn't ported to ZoL until recently but it definitely doesn't look like a ZoL-exclusive bug.

Not to mention that the issue description doesn't say it's a data loss bug. It's a bug that means that ZFS send would not include holes in very specific scenarios. On-disk data would still be safe as far as I can see (though I'm not an FS expert by any stretch).
