Yeah, that has always bugged me too.  I considered renaming it 'issued',
or something, as part of this patchset but thought we could do it later.

While we're on this topic, I'm nervious that we increment it when
do_direct_IO fails.  It might be sound, but that we consider it the
amount of work "transferred" for dio->end_io makes me want to make sure
there aren't confusing corner cases here.
