This policy used to be unconditionally applied by udev, but there is no reason to make userspace be involved in this and in the future udev will not be doing it by default.

Signed-off-by: Tom Gundersen <t...@jklm.no> Cc: Jiri Kosina <jkos...@suse.cz> Cc: Greg Kroah-Hartman <gre...@linuxfoundation.org> --- Hi, I don't have the right hardware for this, so it has only been compile-tested. I'm therefore sending it as an RFC only. Mainly I want to bring it to people's attention that it would be great to get this feature into the kernel as we want to drop it from udev.
