However, bdrv_get_aio_context from block.c already does this verification itself, also returning qemu_get_aio_context() if bs is NULL: AioContext *bdrv_get_aio_context(BlockDriverState *bs) { return bs ? bs->aio_context : qemu_get_aio_context(); } This patch simplifies blk_get_aio_context to simply call bdrv_get_aio_context instead of replicating the same logic.
