Subject: kmemleak and SLAB

Hi,

When I try to use kmemleak with the SLAB allocator set I receive this
message when booting 3.1-rc8:

[   28.480569] kmemleak: Cannot allocate a kmemleak_object structure
[   28.480593] kmemleak: Kernel memory leak detector disabled
[   34.428037] CPA self-test:
[   34.435881]  4k 259968 large 0 gb 0 x 259968[b0000000-ef77f000] miss 0

[   34.458407] ok.
[   38.754032] wlan0: no IPv6 routers present
[   67.666048] kmemleak: Automatic memory scanning thread ended

All is fine when using SLUB. On another run I also got an error about an
ODEBUG oom so I wonder if this is indicative of another problem...
