Also why doesn't this use init_sync_kiocb?

I'm not sure I want ki_flags.

Why?

I'm not sure I want ki_flags setting from f_iocb_flags I should've said.  I'm
not sure how the IOCB_* flags that I import from there will affect the
operation of the synchronous read splice.  IOCB_NOWAIT, for example, or, for
that matter, IOCB_APPEND.
