    Not related to RCU implementation.

    rcutorture (test module) patch independent of the implementation changes.

    srcu (sleepable rcu) patches independent of the core RCU implementation
    changes in the patchset. You can queue these up either before
    or after srcu.

    rcutorture fix patches independent of rcu implementation changes
    in this patchset.

    Heh. I can always re-submit against -mm after I wait for a day or two
    for comments :) Or I can wait. I think rcutorture patches are
    fairly safe to merge and should go in soon. srcu and the patchset
    I mailed today should probably get more testing in -mm before
    going in.
