From mboxrd@z Thu Jan 1 00:00:00 1970 From: Robert Love Subject: [PATCH 37/64] libfc: simplify fc_lport_rport_callback Date: Tue, 25 Aug 2009 14:01:44 -0700 Message-ID: <20090825210144.1553.17750.stgit@localhost.localdomain> References: <20090825205826.1553.94414.stgit@localhost.localdomain> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from mga03.intel.com ([143.182.124.21]:27829 "EHLO mga03.intel.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S932105AbZHYVBn (ORCPT ); Tue, 25 Aug 2009 17:01:43 -0400 In-Reply-To: <20090825205826.1553.94414.stgit@localhost.localdomain> Sender: linux-scsi-owner@vger.kernel.org List-Id: linux-scsi@vger.kernel.org To: James.Bottomley@HansenPartnership.com, linux-scsi@vger.kernel.org Cc: Joe Eykholt , Robert Love From: Joe Eykholt The lport rport callback can only be called for the dNS rport, since its the only rport who's ops point to that function. Remove unnecessary checking and debug messages. Put the locking outside the switch statement as a simplification.
