    I didn't need the callbacks to sleep too, I just needed the read-side
    srcu bit.

    There's an argument against making the callbacks able to sleep like that
    in that you typically want to minimize the amount of work done in the
    callbacks, allowing them to sleep invites to callbacks that do _way_ too
    much work.

    I haven't made my mind up if I care yet.. :-)
