From efc75e2a4cf7dfa62c7ccaa9a1016f27e5519003 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 18 Jan 2018 13:43:45 +0100 Subject: block: rename .bdrv_create() to .bdrv_co_create_opts() BlockDriver->bdrv_create() has been called from coroutine context since commit 5b7e1542cfa41a281af9629d31cef03704d976e6 ("block: make bdrv_create adopt coroutine"). Make this explicit by renaming to .bdrv_co_create_opts() and add the coroutine_fn annotation. This makes it obvious to block driver authors that they may yield, use CoMutex, or other coroutine_fn APIs. bdrv_co_create is reserved for the QAPI-based version that Kevin is working on.
