I'd much rather use the ioend processing infrastructure for this rather
the reinventing another deferral method.  This series:

https://git.infradead.org/?p=users/hch/misc.git;a=shortlog;h=refs/heads/iomap-pi

has the small patches enabling it for reads, and I will post a rebased
and updated version soon.
