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. > > -- > Bojan > -barry -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
