    USB: add USB-Persist facility · 0458d5b4
    Alan Stern authored
    This patch (as886) adds the controversial USB-persist facility,
    allowing USB devices to persist across a power loss during system
    The facility is controlled by a new Kconfig option (with appropriate
    warnings about the potential dangers); when the option is off the
    behavior will remain the same as it is now.  But when the option is
    on, people will be able to use suspend-to-disk and keep their USB
    filesystems intact -- something particularly valuable for small
    machines where the root filesystem is on a USB device!
