From 45d9478da106c749203056f56e94d0e370dfac87 Mon Sep 17 00:00:00 2001 From: Vladimir Sokolovsky Date: Fri, 7 Dec 2007 20:32:03 -0800 Subject: [PATCH] RDMA/cma: Reenable device removal on passive side Enable conn_id remove on the passive side after connection establishment. This corrects an issue where the IB driver can't be unloaded after running applications over RDS. The 'dev_remove' counter does not reach 0 for established connections on the passive side. This problem is limited to device removal, and only occurs on the passive side if there are established connections.
