This is the seventh take of implement ata_link patchset. This patchset contains 14 patches which can be categorized as follows. #01-02: implement ata_link #03-06: make libata deal with link instead of port #07-09: misc link stuff (link init, reset_tries, ata_link_abort()) #10-14: add ap->pmp_link[] and update libata to deal with multiple links ata_link abstracts PHY and sits between ata_port and ata_device. The following attributes are moved to ata_link from ata_port. - active command state (active_tag, sactive) - [hw_]sata_spd_limit - eh_info and eh_context - device array With above and a few extra fields, a link can handle attached devices including qc management and EH/hotplug. This patchset makes libata ready to handle PMP links. Changes from the last take[L] are. * adapted to the current upstream * drivers/scsi/libsas/sas_ata.c updated This patchset is against libata-dev#upstream (5ee30f070f467aaae027f03ef6772128a887b1a3) Thanks. -- tejun [L] http://thread.gmane.org/gmane.linux.ide/21510
