Have to say that while it doesn't change the attributes here, it might require still to be revisited by security people, if they wish.

Ideally I want to get rid of all of the "non-standard" users that set random modes of sysfs files, as we get it wrong too many times.

Why you didn't send that patch to the sysfs maintainer is a bit odd... :) I should be taking this whole series through my tree.

I made a rule for this at one point, but there are cases where the functions have the wrong names, and then these functions may be used elsewhere. julia -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
