The new system ran basically all weekend doing kernel compiles: no leak. But, I added some memory pressure, and made it start allocating a bunch of hugetlbfs pages. That made this bug kick in there too. It's somewhat hard to tell, but I _think_ the leaking is correlated with compaction activity. I'm trying a bisect now. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
