No, REQ_FUA does not oblige us to make sync. REQ_FUA is translated into IOCB_DSYNC. It is IOCB layer job to datasync this exact request. Also REQ_FUA usually is coupled with REQ_PREFLUSH and we already handle that.
We do this only for metadata in previous patches - pure data pios do not handle it. And you are right about REQ_PREFLUSH but i think the vfs layer will handle it along the sync - which is translated to PREFLUSH+FUA
