I have prepared the combined patch for kmemleak porting to MIPS. After
applying the patch and enabling the kmemleak in Kernel, I can see one
kernel memleak reported during booting itself:

If you for the kmemleak scan (via echo) a few times, do you get more
leaks? The udp_table_init() function looks like it could leak some
memory but I haven't seen it before. I'm not sure whether this is a
false positive or a real leak.

Please let me know your comments.

I think the last line should be more like:
