    Please keep them!

    Again, based on what line of reasoning? Again, the obvious lines
    of reasoning do not apply.

    From my earlier message (

    Agreed, in that I know of no binary module that uses RCU. However,
    I cannot -prove- that there is no such module.

    IOW, I am also not 100% sure that there is really no binary-only module
    using these symbols by -anyone-, including someone -other- than IBM.
    In addition, I know of no way that -anyone- could possibly be 100% sure
    that there is really no binary-only module using symbols. Hence the
    approach of providing the year "grace period" before transitioning to

    I am not convinced that the risk of usage increases significantly.
    However, even if someone does start using them in a binary module, they
    will have been warned. Yes, someone could possibly ignore the warning.
    They -still- will have been warned, so that any "damage" would be
    self-inflicted. Therefore, as noted earlier, the symbol transitions
    to EXPORT_SYMBOL_GPL() one year after its inclusion, regardless of any
    people who ignored warnings.

    Thanx, Paul
