Clearing reference bits? Ummm... That is a pretty inaccurate measure since reclaim can remove pages and revert the reference bits.

Would it be possible to sync up with the people doing the page table interface? Could we somehow consolidate smaps and numa_maps? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
