    [SCSI] libsas: execute transport link resets with libata-eh via host workqueue · 81c757bc
    Dan Williams authored
    Link resets leave ata affiliations intact, so arrange for libsas to make
    an effort to avoid dropping the device due to a slow-to-recover link.
    Towards this end carry out reset in the host workqueue so that it can
    check for ata devices and kick the reset request to libata.  Hard
    resets, in contrast, bypass libata since they are meant for associating
    an ata device with another initiator in the domain (tears down
    affiliations).
    
    Need to add a new transport_sas_phy_reset() since the current
    sas_phy_reset() is a utility function to libsas lldds.  They are not
    prepared for it to loop back into eh.
