Actually you are removing a function and adding another.

Better to reuse the macro, it can disappear during the disconnection
causing a use-after-free reading next field.

Basically you inlined red_channel_client_disconnect_if_pending_send.
So basically a RedChannel function which calls lot (4) of RedChannelClient
functions. Well... not a regression but I don't see the gain.
If you are afraid of a public function maybe an header to shared private
communication between RedChannel and RedChannelClient is an idea.
If you are afraid of object size and you want the function to be inlined
I would push for LTO or have a single module compilation.
