Exactly. I hope the page-pin will avoid me having to serialize the KVM page fault against the start/end critical section. BTW, I wonder if the start/end critical section API is intended to forbid scheduling inside it. In short I wonder if GRU can is allowed to take a spinlock in _range_start as last thing before returning, and to release that same spinlock in _range_end as first thing, and not to be forced to use a mutex. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
