[PATCH v5 12/15] block/nvme: Replace BDRV_POLL_WHILE by AIO_WAIT_WHILE |
Date: |

BDRV_POLL_WHILE() is defined as:
#define BDRV_POLL_WHILE(bs, cond) ({ \
BlockDriverState *bs_ = (bs); \
AIO_WAIT_WHILE(bdrv_get_aio_context(bs_), \
cond); })
As we will remove the BlockDriverState use in the next commit,
start by using the exploded version of BDRV_POLL_WHILE().
