https://gerrit.osmocom.org/#/c/12625/2/include/osmocom/bsc/codec_pref.h
File include/osmocom/bsc/codec_pref.h:

https://gerrit.osmocom.org/#/c/12625/2/include/osmocom/bsc/codec_pref.h@24
PS2, Line 24: 		     const struct gsm_bts *bts, enum rate_pref rate_pref);
in ch_mode_rate, we add a 'bool full_rate', and we also add a 'rate_pref'?
That seems redundant to me / more complex for error checking, because I could technically pass 
ch_mode_rate->full_rate = false and rate_pref = RATE_PREF_HR.

would it make more sense to add an enum rate_pref to channel_mode_and_rate, instead of the bool?
Or instead of enum rate_pref, add a "bool strict_rate_pref", to say whether the ch_mode_rate->full_rate flag is important or can be overruled?

const struct ...

PS2, Line 305: static int check_voice_stream_needed(struct gsm_subscriber_connection *conn, struct osmo_fsm_inst *fi)
(we already have a flag around called "requires_voice_stream", so prefer if this is called "check_requires_voice_stream()")


https://gerrit.osmocom.org/#/c/12625/2/src/osmo-bsc/assignment_fsm.c@324
PS2, Line 324: 		result_pref = false;
don't understand the name 'result_pref' ... from surrounding code I guess 'requires_voice' is better?
