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.
