Changes since v7: http://marc.info/?l=linux-scsi&m=132739159230095&w=2
1/ Dropped "libsas: feed the scsi_block_when_processing_errors() meter"
[1]. Patches 1-3 are just resends of the patches affected by that
rebase.
2/ Fixed up the phy identify data that is exported to userspace.
sas_phy/phyX/device_type and sas_phy/phyX/target_port_protocols are
now populated more reliably. Patches 4-5
3/ User-disabled ssp phys are now no longer inadvertantly re-enabled by
error recovery (they need an explicit reset from userspace). This
enables scripted hotplug testing. Patches 6-8
4/ Fixed up the eh_strategy_handlers to prevent them being called from
outside eh context, added an abort handler, and made sure all resets
are notified to the lldd. Patches 9-12
5/ A small diet for sas_task to move slow path infrastructue out of the
fast path use case. Patch 13
