| |
My laptop drive seems to be waking up more often today and I suspect it's somehow ext3/kjournald that's to blame. Does it obey the timings in /proc/sys/vm/bdflush or does it have its own flush timer?
There's a more general problem with VM on laptops which is that the system doesn't have any notion of spun-down disks. Flush intervals should be short when the disk is running and long when it isn't and decisions about which pages to discard or swap might be improvable. Pre-emptive swap when the disk is spun down is a loss..
