From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bart Van Assche Subject: [PATCH 00/19, v5] Make ib_srp better suited for H.A. purposes Date: Fri, 26 Oct 2012 14:44:43 +0200 Message-ID: <508A85BB.1000505@acm.org> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: "linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org" , linux-scsi , David Dillow , Roland Dreier List-Id: linux-scsi@vger.kernel.org This patch series makes the ib_srp driver better suited for use in a H.A. setup because: - multipathd is notified faster about transport layer failures. - Transport layer failures reliably result in SCSI host removal. - Switchover can be triggered explicitly by deleting an initiator device. - Disconnecting from a target without unloading ib_srp is now possible. This patch series is also available here: http://github.com/bvanassche/linux/commits/srp-ha And a backport of this patch series to kernels 3.6 and before is available here: http://github.com/bvanassche/ib_srp-backport. Changes since v4: - Added a patch for removing SCSI devices upon a port down event Changes since v3: - Restored the dev_loss_tmo and fast_io_fail_tmo sysfs attributes. - Included a patch to fix an ib_srp crash that could be triggered by cable pulling. Changes since v2: - Addressed the v2 review comments. - Dropped the patches that have already been merged. - Dropped the patches for integration with multipathd. - Dropped the micro-optimization of the IB completion handlers.
