From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sasha Khapyorsky Subject: [PATCH] opensm/osm_get_port_by_lid(): use faster cl_ptr_vector_get() Date: Tue, 29 Sep 2009 13:02:15 +0200 Message-ID: <20090929110215.GK26931@me> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: OpenIB , linux-rdma Cc: Hal Rosenstock List-Id: linux-rdma@vger.kernel.org Use faster cl_ptr_vector_get() call instead of cl_ptr_vector_at(). In this way eliminate 'stat' variable needs.
