    The changes seem easy enough and I need to respin at least for the
    lkdtm changes, and probaby also for a pending fix in the low-level
    x86 code that will hopefully be picked up for 5.9.

    But the more important questions is: how do we want to pick the series
    up? Especially due to the splice changes I really want it to be in
    linux-next as long as possible.
