[Qemu-devel] when to bdrv_co_flush()?

[lihuiba]

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!
