Tejun, I have a confusion regarding the following statement. "along with previously completed writes on bio completion" I thought REQ_FUA just gurantees that bio/req carrying REQ_FUA flag is on disk platter. It does not gurantee anything about other requests which completed before this bio/req and might still be in non volatile caches of device.
