This series drops useless extern annotations and adds some coroutine_fn in the
9pfs and fsdev code.

It does not change any functionality.

All these functions use the v9fs_co_run_in_worker() macro, and thus always
call qemu_coroutine_self() and qemu_coroutine_yield().

Let's mark them to make it obvious they execute in coroutine context.

From: Greg Kurz @ 2016-10-02 16:06 UTC (permalink / raw)
  To: Greg Kurz; +Cc: Aneesh Kumar K.V, qemu-devel

All these functions either call the v9fs_co_* functions which have the
coroutine_fn annotation, or pdu_complete() which calls qemu_co_queue_next().

Let's mark them to make it obvious they execute in coroutine context.
