    Hi FrankH,

     The patch seems has connection with this

     www.kernel.org/doc/ols/2010/ols2010-pages-9-18.pdf

    You can see the section 4.3 fast device reactivation.
    It does the similar thing  as STR, but drivers status are kept in
hibernation image instead of main memory.
    I guess this is why this patch comes out.

    In the current device driver model, there are no appropriate handling
specific to
    hibernation_suspend/hibernation_resume ops.

    So they make their own interface/platform drivers.
