Subject: kmemleak - percpu reliability?

Hi,

Yesterday I found the bug fixed by this commit:
https://git.kernel.org/cgit/linux/kernel/git/jberg/mac80211.git/commit/?id=e6436be21e77e3659b4ff7e357ab5a8342d132d2

The first case can easily be reproduced by running:

# iw wlan0 interface add wlan0 type monitor

(reusing the name "wlan0" twice, the command should fail)

I tried to see what happens with kmemleak, but for some reason it won't
report it even with forced rescan etc.

Am I missing something?

Thanks,
johannes
