Subject: [PATCH bluetooth-next 5/5] Rename process_data and lowpan_process_data.
Date: Sat, 18 Oct 2014 08:09:13 +0100	[thread overview]
Message-ID: <1413616153-7562-6-git-send-email-mtownsend1973@gmail.com> (raw)
In-Reply-To: <1413616153-7562-1-git-send-email-mtownsend1973@gmail.com>

As we have decouple decompression from data delivery we can now rename all
occurences of process_data in receive path.
