Subject: [PATCH 1/2] uapi: update includes for drm content when no kernel API exists
From: "Luis R. Rodriguez" <mcgrof@...not-panic.com>
The UAPI changes split kernel API and userspace API
content onto two separate header files. The userspace
API drm content was moved to include/uapi/drm/ with the
same file name while kernel specific API content was
kept under include/drm/ with the same file name. When
one file was split into two files the kernel header
includes the uapi header and a UAPI prefix was added to
the uapi header for its header guard. When there was no
kernel API content found the uapi header file was the
only one that was kept and the original guard for the
header file was kept. In this particular case the
original users of this header file were not modified
and the uapi header file is expected to be picked up
by path.
This may work well at compilation on the kernel but when
backporting this creates a few complexities. To help with
backporting [0] lets be explicit about the new uapi path
when there is no respective kernel API header file. For
more details on the UAPI changes see the lwn article on
this [1].
