From ab626d1a68d1aee19a5c7d889b9fbeace6a92b41 Mon Sep 17 00:00:00 2001 From: Zhao Hongjiang Date: Fri, 15 Nov 2013 14:16:37 -0800 Subject: [PATCH] IB/cm: Convert to using idr_alloc_cyclic() Commit 3e6628c4b347 ("idr: introduce idr_alloc_cyclic()") adds a new idr_alloc_cyclic() routine and converts several of these users to it. This is just a missed one - add it.
