Btw is DRM_MAJOR 226 consider uapi? I don't see it in uapi headers.
It's not in the headers, but it's de facto uAPI, as seen in libdrm:

99:#define DRM_MAJOR 226 /* Linux */
I suspected it would be yes, thanks.
I was just wondering if stat(2) and a chrdev major check would be a
solid criteria to more efficiently (compared to parsing the text
content) detect drm files while walking procfs.
