Rebase against xfs-linux for-next, then send Chandan a pull request.

That would have gotten done this morning, only now everything's on hold
again while we wait for the mm maintainers to get around to reviewing
the patches in the xfile diet v3 series:
https://lore.kernel.org/linux-xfs/87frxva65g.fsf@debian-BULLSEYE-live-builder-AMD64/T/#m99f2f7e1fb221c4d7f5a00f249119d570ab70fce

Yes I know you already reviewed all of them (again, thank you!) but
apparently your RVB tag is not good enough for the very high standards
of the kernel community.  In the mean time, the only thing we can do is
wait patiently and hope that one of the maintainers can free up enough
time to take a look.
