I suppose I could have added a sysfs flag exposing the sleep state and had userspace check that first, but it seems silly to add a whole new ABI and to check the power state rather than simply fixing the existing command to not wake the disk in order to tell userspace what we already know using a code path we already have. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJSsF61AAoJEI5FoCIzSKrwMvEH/3IOti/mKMvwm6b0ie3+knMT QLDPuq7K/7qkbHPuSD/Bm2OwJR69SRFYSUYLpLL/u8r1JAgRKJJx1YywFgpmRJm9 43bE+R3uXhpYxSy5zf0s8T1VbNalWWVZKjfrrXjJic+H37y0E/lZcUtq8fSPnNu9 xNXLZ2/dkmWbAw+zu2Zszao3zPeYtP3bqhYa6HFZYDKxFEl4IPg9uKnQ9rAq7D/Y /WtqOlckSqWdPSLKbQh3nbEd9dvdIqEx2wuqK8jthoHR0+HFoAGRqRHY6PKLKal5 bnxl7T8Wr6dRlb13vZZy6TwHU6HRxK6w9vCmRhSg04hHvtA8q2DmDM5Go+4PZEg= =w2m9 -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
