Subject: [PATCH 3/5] ipc: rename ipc_obtain_object
Date: Sat, 6 Jun 2015 06:37:58 -0700 [thread overview]
Message-ID: <1433597880-8571-4-git-send-email-dave@stgolabs.net> (raw)
In-Reply-To: <1433597880-8571-1-git-send-email-dave@stgolabs.net>
... to ipc_obtain_object_idr, which is more meaningful
and makes the code slightly easier to follow.
