As described in commit 2bc0576 ("block: don't make REQ_POLLED imply REQ_NOWAIT"), which fixed the same issue for the block device node, there are valid cases to poll for I/O completion without REQ_NOWAIT. Additionally, sing REQ_NOWAIT for file system writes is currently not supported as file systems writes are not idempotent and would need a retry of just the bio and not the entire operation to be fully supported. Switch iomap to set REQ_POLLED and remove the now unused bio_set_polled helper. Signed-off-by: Christoph Hellwig <hch@lst.de>
