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.
