    I never got a reply about this. Again: how can the modern slab allocator
    avoid the need for internode alignment in order to prevent cacheline
    pingpong on vsmp? Because I'm going to resubmit the SMP_ALIGN patch.

    Also, the last I heard about the HWCACHE_ALIGN from you is that it didn't
    make sense... I see it's merged now, which I appreciate, but I think it is
    really important that we're on the same page here, so let me know if it
    still doesn't make sense.

    Thanks,
    Nick
