[PULL 25/50] 9p: add missing coroutine_fn annotations
Posted by Kevin Wolf 2 years, 5 months ago
From: Marc-André Lureau <marcandre.lureau@redhat.com>

Callers of coroutine_fn must be coroutine_fn themselves, or the call
must be within "if (qemu_in_coroutine())".  Apply coroutine_fn to
functions where this holds.
