Subject: [PATCH 3/4] sysvipc: properly name ipc_addid() limit parameter
Date: Thu, 31 Aug 2017 10:20:48 -0700 [thread overview]
Message-ID: <20170831172049.14576-4-dave@stgolabs.net> (raw)
In-Reply-To: <20170831172049.14576-1-dave@stgolabs.net>
This is better understood as a limit, instead of size;
exactly like the function comment indicates. Rename it.
