      libata: export host controller number thru /sys · 1757d902
      David Milburn authored
      As low-level drivers register their host controller(s), keep track
      of the number of controllers and export thru /sys in a <host.port>
      format so that udev can better match up port numbers with a
      specific controller.
      
      # pwd
      /sys/devices/pci0000:00
      # find . -name 'ata*' -print
      
      (2nd controller with port multiplier attached)

      [libata] enable ata port async suspend · 966f1212
      Lin Ming authored
      This saves devices suspend/resume time.
      
      Tested system suspend/resume with SATA IDE/AHCI mode 3 times.
      Below is the time took for devices suspend/resume.
