    [SCSI] libsas: convert to libata new error handler · c299190b
    James Bottomley authored
    The conversion is quite complex given that the libata new error
    handler has to be hooked into the current libsas timeout and error
    handling.  The way this is done is to process all the failed commands
    via libsas first, but if they have no underlying sas task (and they're
    on a sata device) assume they are destined for the libata error
    handler and send them accordingly.
    
    Finally, activate the port recovery of the libata error handler for
    each port known to the host.  This is somewhat suboptimal, since that
    port may not need recovering, but given the current architecture of
    the libata error handler, it's the only way; and the spurious
    activation is harmless.
