Subject: [PATCH 5/7] RDMA/cxgb4: remove db_drop_task.
Date: Fri, 11 Mar 2011 16:30:32 -0600	[thread overview]
Message-ID: <20110311223032.16418.78659.stgit@build.ogc.int> (raw)
In-Reply-To: <20110311222826.16418.43582.stgit-T4OLL4TyM9aNDNWfRnPdfg@public.gmane.org>

Unloading iw_cxgb4 can crash due to the unload code trying to use
db_drop_task, which is uninitialized.  So remove this dead code.
