Can you elaborate?
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.
