    Subjectmemory-controller patch fails to boot in qemu [mmotm]
    Hi,

    in mmotm-2009-07-30-05-01, the patch named
    memory-controller-soft-limit-organize-cgroups-v9.patch
    causes qemu fail to boot with tons of:
    BUG: scheduling while atomic: async/2/480/0x10000002

    Looks like an omitted unlock. I don't see anything suspicious in the
    patch though.

    The W taint flag is from:

    and is unrelated (it was always there).
