A big reason for that is that it's not in my inbox for me to review, these messages I flagged as unhelpful aren't going to help with that if only because I don't want to create the impression that such behaviour achieves results. > FWIW I added the ability to open any CS, even those claimed by kernel > drivers.

This doesn't seem like an obviously good idea - having userspace be able to interact with a device without a running kernel driver knowing about it doesn't seem like something that will end well. --suYuRLWiGRtbsVTA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJVQollAAoJECTWi3JdVIfQJ+4H/jofIikM6JHNgzNmhsAV2zsO RzNP/ldc8YohN7WzY3XLTvxYOrzDf4GfWVf73U8unB3nADrp65MEJJvmhtXevJJr 2trFAZBfaughHcth2uEZy/OVRzjgsfegg8HuZg5DHUSRmISY+mVnj9aNtVAvUS6p gH7cHeaxr+mvzNV7MmxwDjA8gIW9YOaPM59Qpbv99gIHEhZhl60hg8A+w0EhR3q9 lvE6nSJ3U71uGlwjHtBEl+GbCGJWEivCwUdOtJDUlmnUHHgb7DohfldTXwHDiZ8Q qLIVPSEUHTusUjMho1JEOW7Hb7TtHGFlEPE5fSp+0BgiSr+C8MjboOs+1WWN/bA= =xlXQ -----END PGP SIGNATURE----- --suYuRLWiGRtbsVTA-- -- 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/
