    It's a rare pleasure to be presented with such a straightforward bug!

    stable/longterm: well, I don't mind asking akpm to add a Cc: stable,
    but don't be surprised if he prefers not: although it was a regression
    back in 2.6.23, it's not a security issue, and the lack of interest
    between then and now doesn't make a strong argument for it.

    Andrew, if you're so inclined, please add a Cc: stable@kernel.org
    to [PATCH] shmem: let shared anonymous be nonlinear again

    Thanks,
    Hugh
