We use the RQ_POSTPONED flag to mark a request for several reasons. It may be a conflicting request in a dual-primary setup, where conflict detection and resolution on the peer decided that this request needs to be re-submitted, it needs to re-enter drbd_make_request() to fix the data divergence caused by these conflicting, partially overlapping, quasi-simultaneous requests. In this case we need to mark the corresponding area as out-of-sync, before we call drbd_al_complete_io(). We also use the RQ_POSTPONED flag to just "push back" a request, before even processing it, if IO is suspended for some reason. In this case, as this request was neither submitted nor sent yet, we must not touch the bitmap.
