Is this still a problem with 3.9 and later kernels? Please try to reproduce it on 3.13. If it does reproduce, could you try to pinpoint the problem with kmemleak? Look into Documentation/kmemleak.txt which should identify where these leaks are coming from with your slab allocator of choice. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
