Greg, please hold on with this backport. I would like to get
http://lkml.kernel.org/r/20170328124312.GE18241@dhcp22.suse.cz resolved.
So far I believe the patch is simply not needed. I might be wrong but I
would like to hear the explanation first. Using NOIO, NOFS context is
misunderstodd very often and I suspect this is the case here as well.
