Sorry I missed this Rik. The rsslimit patch is now too old
to apply to the mm tree because of one of my patches.
To fix this you need to be able to check rsslimit before
clearing referenced bits, and possibly not clear referenced
bit at all.
Its obviously inefficient to do to check ptes twice, so probably
just doing it once would be OK, you'd just need to do something
like:
if (referenced && dont_clear_referenced)
SetPageReferenced(page);
at the end.
