The first ones were in 2.6.9-rc2. Well, "[PATCH] make shrinker_sem an rwsem" was in -rc1; I guess that would be worthwhile testing, if only because it touches vmscan.c It would be nice to find out what is going on before 2.6.10 gets released, but Mats isn't going to be able to do any more testing for the moment. Andrew, what should we do?
