[PATCH 02/10] UAPI: Make uapi/linux/irqnr.h non-empty

From: David Howells
Date: Wed Oct 17 2012 - 10:15:32 EST

uapi/linux/irqnr.h was emitted by the UAPI disintegration script as an empty
file because the parent linux/irqnr.h had no UAPI stuff in it, despite being
marked with "header-y".

Unfortunately, the patch program deletes the empty file when applying a kernel

It's not clear why this file is part of the UAPI at all. Looking in:


there's nothing there but a header reinclusion guard and a comment.

So just stick a comment in there as a placeholder.

Without this, if the kernel is fabricated from, say, a tarball and a patch, you
can get this error when building x86_64 or usermode Linux (and probably

include/linux/irqnr.h:4:30: fatal error: uapi/linux/irqnr.h: No such file or directory
