Subject: Memory leaks from swapper, wpa_supplicant, glxgears

Hello there,

I have enabled CONFIG_KMEMLEAK and I am finding some memory leakage apparently caused by "swapper" process; I have also had leaks from glxgears and wpa_supplicant, but they can be triggered only once (e.g. restarting wpa_supplicant does not trigger more leaks).

The swapper leaks seem to be an incremental decimal string, starting from "0" to "10", while the wpa_supplicant leaks were the AP ESSID (not in attached report).

Best regards,
- --
