Subject: [PATCH 01/11] RDMA/cxgb4: Detach from the LLD after unregistering with the RDMA core.
Date: Thu, 20 May 2010 16:57:27 -0500 [thread overview]
Message-ID: <20100520215727.32394.90669.stgit@build.ogc.int> (raw)
In the RDMA core unregister path, kernel users will be calling down
into the T4 provider to release resources. So we cannot detach from
the LLD until this process completes.
