Re: Locks and the FSB

[Elad Lahav <elad_lahav@xxxxxxxxxxxxxxxxxxxxx>]

I'm wondering if the high event counts following spin_unlock_irqrestore() are due to an 
OProfile quirk. OProfile depends on interrupts, which are disabled inside the critical 
section protected by the spin lock. It may end up accounting for all events that occurred 
inside the critical section immediately after the processor exits this section.
