Well, I do wish the CC list had been setup a bit more deliberately.
Especially as this is a resend, and I didn't even know about any of this
before Christian pointed me this way the other day.
Checking lore, I can't even see all the patches. So while it may be
annoying, I do think it may be a good idea to resend the series so I can
take a closer look as well. I do think it's interesting and I'd love to
have it work in a non-blocking fashion, both solving the issue of splice
holding the pipe lock while doing IO, and also then being able to
eliminate the pipe_clear_nowait() hack hopefully.
