The fix was committed to CURRENT on Oct 8th (r213634). The commit message talks about MFC after a week, however to me it looks like the fix hasn't made it to 8-STABLE yet. Also, there seems to be a related commit r213673 which essentially reverts r213634 and has a more general approach to handling ioflags with zfs. This commit was on Oct 10th, again 1 week MFC grace period, again not in 8-STABLE yet, at least to my knowlegde. Maybe MFC was simply forgotten, maybe there's a good reason to delay it, I don't know. We're using my patch (the one mentioned in the PRs) for now and append-only works as intended. Applying the changes in r213673 to 8-STABLE might be an option too, if you're considering patching to get the append flag working. Anyway, hopefully one of these fixes gets MFCd to 8-STABLE soon.
