Thanks. I left one comment about patch 1 in that subthread. The general
idea of this patchset seems fine, but: what about write_iter? Can't we
convert both of them? 1/3 - read_iter, 2/3 - write_iter, 3/3 - add the
generic splice helpers. I ask because it seems weird to keep around the
old thing (which sounds like is being gradually removed?) alongside the
new thing.
