See http://www.infradead.org/rpr.html Only fall back from hardware Write Zeroes failures when blkdev_issue_write_zeroes returns -EOPNOTSUPP; Note that blkdev_issue_write_zeroes turns any failure into -EOPNOTSUPP when the write zeroes queue limit has been cleared to 0, so this still catches all I/O errors where the driver detected missing support for the hardware acceleration.
