That lets data writes run after a failed preflush and can complete the bio successfully despite the failed ordering barrier.</p> <p>Run the REQ_PREFLUSH flush synchronously before touching the bio data and complete the bio with the flush error if it fails. Keep asynchronous flush chaining for REQ_FUA. At that point, data copy has completed and the parent bio can wait for the chained flush bio.</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>nvdimm: pmem: keep PREFLUSH before data writes</p> <p>pmem_submit_bio() records a REQ_PREFLUSH error, but continues to copy the bio data and can later overwrite the error with a successful REQ_FUA flush.
