block: clear iocb->private in blkdev_bio_end_io_async()
iocb_bio_iopoll() expects iocb->private to be cleared before releasing the bio. We already do this in blkdev_bio_end_io(), but we forgot in the recently added blkdev_bio_end_io_async(). Fixes: 54a88eb838d3 ("block: add single bio async direct IO helper") Cc: asml.silence@gmail.com Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Ming Lei <ming.lei@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/20220211090136.44471-1-sgarzare@redhat.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
