From my perspective, once something has -mm dependencies it needs to
go through Andrew's tree, and if it's going through Andrew's tree I
think that means the reflink side of this needs to wait a cycle as
there is no stable point that the XFS tree could merge to build on top
of.
The last reviewed-by this wants before going through there is Naoya's
on the memory-failure.c changes.
