Subject: [PATCH v5 12/15] block/nvme: Replace BDRV_POLL_WHILE by AIO_WAIT_WHILE
Date: Thu, 20 Aug 2020 18:58:58 +0200	[thread overview]
Message-ID: <20200820165901.1139109-13-philmd@redhat.com> (raw)
In-Reply-To: <20200820165901.1139109-1-philmd@redhat.com>

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().
