pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bsc/+/28046 ) Change subject: Introduce new signal S_NM_RUNNING_CHG and implement it for rcarrier,bbtransc ...................................................................... Introduce new signal S_NM_RUNNING_CHG and implement it for rcarrier,bbtransc This allows different parts of the code to hook to some signals which allow start/stopping processes based, for instance, on whether C0 is available or not. This can be later used by paging or CBSP code. Also ACC code can be ported to this new system (acc_ramp_nm_sig_cb()). Same signal can be used for other NM objects, but is left unimplemented until there's use for them.
