Ok? FWIW, updated (with fixes) and force-pushed. Added piece: default_file_splice_read() converted to iov_iter. Seems to work, after fixing a braino in __pipe_get_pages(). Changed: #4 (sleep only in the beginning, as described above), #6 (context changes from #4), #10 (missing get_page() added in __pipe_get_pages()), #11 (removed pointless truncation of len - ->read_iter() can bloody well handle that on its own) and added #12.
