Subject: [libsas PATCH v12 00/11] libsas eh, discovery, suspend, and fixes
Date: Wed, 21 Mar 2012 23:31:54 -0700 [thread overview]
Message-ID: <20120322063127.22036.23206.stgit@dwillia2-linux.jf.intel.com> (raw)
Changes since v11: http://marc.info/?l=linux-scsi&m=133170574921314&w=2
This is primarily a collection of fixes to the libsas functionality that
has gone upstream in the initial scsi push for 3.3, but also includes a
revised suspend/resume implementation that was initially posted before
the merge window opened.
1/ PATCH 1: Maciej noticed that the original version of "libsas: cleanup
spurious calls to scsi_schedule_eh" went too far when it deleted
sas_ata_task_abort.
2/ PATCH 3: Hot plug testing incurs 1 minute timeouts, across 3 reset
attempts, for ATA unplugs so provide an option to cut that down to
one reset with a 10 second timeout.
3/ PATCH 4-5: Address long standing kernel panics when hotplugs occur
during the initial scan.
4/ PATCH 6-9: Address corner cases and regressions in device discovery
5/ PATCH 10-11: Revised suspend implementation with a cleaner fix for
the sd-probing vs PM-resume deadlock.
[libsas PATCH v12 01/11] libsas: cleanup spurious calls to scsi_schedule_eh
[libsas PATCH v12 02/11] libsas: trim sas_task of slow path infrastructure
[libsas PATCH v12 03/11] libata: reset once
[libsas PATCH v12 04/11] sysfs: handle 'parent deleted before child added'
[libsas PATCH v12 05/11] scsi_transport_sas: fix delete vs scan race
[libsas PATCH v12 06/11] libsas: unify domain_device sas_rphy lifetimes
[libsas PATCH v12 07/11] libsas: fix false positive 'device attached' conditions
[libsas PATCH v12 08/11] libsas: fix ata_eh clobbering ex_phys via smp_ata_check_ready
[libsas PATCH v12 09/11] libsas, libata: fix start of life for a sas ata_port
[libsas PATCH v12 10/11] scsi, sd: limit the scope of the async probe domain
[libsas PATCH v12 11/11] libsas: suspend / resume support
Note, I rebased the isci branch to move all scsi, libsas and libata
patches to this 'libsas' branch.
The following changes since commit cd8df932d894f3128c884e3ae1b2b484540513db:
