Hi, all

bdrv_co_flush() will flush all cached data to persistent storage, and I'm
wondering whether guest sync() will eventually trigger bdrv_co_flush() be
called. 

Intuitively, guest sync() should trigger bdrv_co_flush() in qemu. But simple

grep gave me a negative answer. So I'm wondering why it's not like what I

suspected.


Thanks!
