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.
