Eventfd notifications became part of the AIO API (it's not even delivered through a new syscall, from the AIO side - same existing aiocb struct and io_submit syscall) once we merged it, so IMHO (AIO && !EVENTFD) would be similar to split AIO in AIO_READ and AIO_WRITE and have (AIO && !AIO_WRITE). Considering that the kernel config, once you unleash the CONFIG_EMBEDDED pandora box, allows you to select (AIO && !EVENTFD) w/out even a warning about possible userspace breakages, this makes it rather a confusing configuration if you ask me. It's not a biggie from the kernel side, just a few ugly errors wrappers around functions. For me AIO (or whatever userspace visible kernel subsystem) should select all the components that are part of the userspace API, but my argument ends here. - Davide -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
