[Qemu-devel] [PATCH 1/8] block: rename .bdrv_create() to .bdrv_co_create_opts()

[Paolo Bonzini <pbonzini@redhat.com>]

From: Stefan Hajnoczi <stefanha@redhat.com>

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.
