Hey Dave,

I was going to start testing these, but I'm having trouble finding a baseline
where they apply cleanly. It looks like xfs/for-next already contains v1 of
the series, and they don't seem to apply cleanly to the current
xfs/xfs-misc-fixes-for-4.4-2 nor to v4.3. The xfs repo I'm looking at is
git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git

What am I missing?

Thanks,
- Ross
