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.

Looks like regular SLAB corruption bug to me. Can you trigget it with SLUB?

Anyway, it seems very unlikely that it's caused by the SLAB changes in -rc1 so I'm CC'ing scheduler and fs folks in case the oops rings a bell.

Pekka
