    ata: ahci: find eSATA ports and flag them as removable · 8a3e33cf
    Manuel Lauss authored
    If the AHCI ports' HPCP or ESP bits are set, the port
    should be considered external (e.g. eSATA) and is marked
    as removable.  Userspace tools like udisks then treat it
    like an usb drive.
    
    With this patch applied, when I plug a drive into the esata port,
    KDE pops up a window asking what to do with the drives(s), just
    like it does for any random USB stick.
    
    Removability is indicated to the upper layers by way of the
    SCSI RMB bit, as I haven't found another way to signal
    userspace to treat a sata disk like any usb stick.
