Subject: [PATCH 04/19] xen: credit2: kill useless helper function choose_cpu
Date: Sat, 18 Jun 2016 01:11:45 +0200	[thread overview]
Message-ID: <146620510554.29766.4276980651226118049.stgit@Solace.fritz.box> (raw)
In-Reply-To: <146620492155.29766.10321123657058307698.stgit@Solace.fritz.box>

In fact, it has the same signature of csched2_cpu_pick,
which also is its uniqe caller.
