    i mean we can load image and decompress them in different threads when
    we reboot from hibernation.
    after i read codes more carefully, that has actually been done by
    lzo_decompress_threadfn().

    here the problem is we didn't seem to get any faster after applying
    your compression patch when doing hibernation on SD/NAND.
    we are trying to figure out the reason.
