Excellent, thanks for getting back quickly. The necessary patches in question are sortof-in-flight but I expect they'll make it in for 3.7. If that happens, it would be very nice if you could test with 3.7 to confirm and if all goes according to plan, I'll do a backport for 3.6-stable and hopefully squash most of the THP-causes-all-and-sundry-to-go-nuts bugs. -- Mel Gorman SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
