Subject: [PATCH v4 05/11] block-coroutine-wrapper.py: default to main loop aiocontext if function does not have a BlockDriverState parameter
Date: Wed, 16 Nov 2022 07:22:35 -0500 [thread overview]
Message-ID: <20221116122241.2856527-6-eesposit@redhat.com> (raw)
In-Reply-To: <20221116122241.2856527-1-eesposit@redhat.com>
Basically BdrvPollCo->bs is only used by bdrv_poll_co(), and the
functions that it uses are both using bdrv_get_aio_context, that
defaults to qemu_get_aio_context() if bs is NULL.
Therefore pass NULL to BdrvPollCo to automatically generate a function
that create and runs a coroutine in the main loop.
