Subject: [PATCH 00/20, v4] Make ib_srp better suited for H.A. purposes
Date: Thu, 09 Aug 2012 15:41:45 +0000 [thread overview]
Message-ID: <5023DA39.7020000@acm.org> (raw)
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 a reconnect.
- Switchover can be triggered explicitly by deleting an initiator
device.
- Disconnecting from a target without unloading ib_srp is now possible.
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.
The individual patches are:
0001-ib_srp-Fix-a-race-condition.patch
0002-ib_srp-Enlarge-block-layer-timeout.patch
0003-ib_srp-Move-QP-state-check-into-srp_send_tsk_mgmt.patch
