    Very good, and thank you very much for all your testing efforts!

    I have added a ten-microsecond delay to __rcu_read_unlock() under a
    new CONFIG_RCU_PROVE_DELAY, and have added this to my testing regimen.
    And I guess I have also added it in a probabilistic manner to the various
    randconfig testing out there. ;-)

    Or will have when it hits mainline, probably 3.7.

    Thanx, Paul
