Hello, mm experts,

I triggered an mm bug today, the full backtrace is here:

http://pastebin.ca/1831436

I am using yesterday's Linus tree.

It's not easy to reproduce this, I got this very randomly.

Some related config's are:

CONFIG_SLAB=y
CONFIG_SLABINFO=y
# CONFIG_DEBUG_SLAB is not set

Please let me know if you need more info.

Thanks.
