Yes, it was not a patch, but the general idea for Catalin ;) You hit the fact that same zone (embedded percpu space) is now in a mixed state. In current kernels, the embedded percpu zone is already known by kmemleak, but with a large granularity. kmemleak is not aware of individual allocations/freeing in this large zone.
It looks like this comes via the bootmem allocator. Maybe we could simply call kmemleak_free() on the embedded percpu space and just track those via the standard percpu API. -- Catalin -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
