From c13295ad219d8bb0e47942d4cfc8251de449a67e Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Fri, 11 Jan 2019 00:25:41 +0100 Subject: binderfs: rename header to binderfs.h It doesn't make sense to call the header binder_ctl.h when its sole existence is tied to binderfs. So give it a sensible name. Users will far more easily remember binderfs.h than binder_ctl.h.

This breaks the current y2038 fix for kernel as we only access and define the timeval struct for non-kernel use cases. But, this was hidden by an another typo in the use of __KERNEL__ qualifier.
