From 687f731bd0729800d9a8a32aa327664bd9d34045 Mon Sep 17 00:00:00 2001 From: Zhao Hongjiang Date: Thu, 23 May 2013 10:37:00 +1000 Subject: [PATCH] drivers/infiniband/core/cm.c: 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.
