+# The "check" target will fail if any of the library headers don't
+# match the kernel DRM headers.  That's intentional.  It's critical
+# that these headers match or things will NOT work correctly.
+#
+# If these headers really need changes, you'll need to update the
+# kernel headers, update the kernel driver code to do the right
+# thing with those updates, and finally update the patches here
+# to make the patched headers match the kernel again.  We could
+# also just delete these lib copies of these headers, but then
+# you would not notice changes when updating to a newer version
+# of the libdrm code, and fail to make necessary updates.
