drbd: announce FLUSH/FUA capability to upper layers Unconditionally announce FLUSH/FUA to upper layers. If the lower layers on either node do not actually support this, generic_make_request() will deal with it. If this causes performance regressions on your setup, make sure there are no volatile caches involved, and mount -o nobarrier or equivalent.
