    Create a 350 processes reading /sys/kernel/debug/kvm/spinlocks/histo_blocked
    file simultaneously in while loop for more than 3 hours on my box.
    Could not reproduce the problem. ( was it the right thing I did to
    reproduce.. not sure..). Wanted to check that because if it had hit the
    problem I can verify fix with same stuff.

    But in any case will try the fix what Konrad/Linus suggested, and come back.
