No, but I did some tests with one of my network performance tools. I imagine that I can *construct* test-cases and add some 'perf stat cs:u' statistics.

There are use-cases where EPOLLEXCLUSIVE can be really helpfull, yes I think that this flag SHOULD be a userspace default. ;-) Hagen -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
