    If you can make it use a lockless list thing that's fine.

    I'm not sure Andrew's CONFIG_ARCH_HAVE_NMI_SAFE_CMPXCHG makes much sense
    for CONFIG_ARCH_HAVE_NMI=n though..

    Anyway, make sure to consolidate net/rds/xlist.h and its users, having
    two lockless lists is one too many.

    But only if the platform has NMIs, otherwise its moot.
