This will usually clear the flags fairly quickly.\n\nIf writing the superblock finds that BIO_RW_BARRIER is -ENOTSUPP, we need to\nresubmit, so introduce function \"md_super_wait\" which waits for requests to\nfinish, and retries ENOTSUPP requests without the barrier flag.\n\nWhen writing the real raid1, write requests which were BIO_RW_BARRIER but\nwhich aresn\u0027t supported need to be retried. So raid1d is enhanced to do this,\nand when any bio write completes (i.e. no retry needed) we remove it from the\nr1bio, so that devices needing retry are easy to find.\n\nWe should hardly ever get -ENOTSUPP errors when writing data to the raid.\nIt should only happen if:\n 1/ the device used to support BARRIER, but now doesn\u0027t.
