    Ah. I wasn't able to see much duplicated code at all, so I wasn't sure
    that we needed to bother about this issue.

    yup, atomic_inc_not_zero() looks like a candidate.

    Let's go with this for now ;)

    I'll assume that you intend to make use of this function soon, and it
    looks safe enough to sneak it into 2.6.37-rc2, IMO. If Linus shouts at
    me then we could merge it into 2.6.38-rc1 via net-next, but I think
    straight-to-mainline is best.
