Patch Set 1:

> At first sight I'm not entirely convinced.
 > 
 > An RLL REL IND indicates release of one SAPI (on either DCCH or
 > SACCH), not release of the radio channel. The MS could release
 > SAPI3 as no SMS transmissions are pending but still keep SAPI 0 for
 > other signaling?
 > 
 > Imagine SMS over SACCH while a call is ongoing.

Yes, I was wondering about that. Our code walks all over that by just flattening the SAPI indicator out completely. It appears this needs a proper revisit and tests to go with it. I opened https://osmocom.org/issues/3060
