UAPI: Make uapi/linux/irqnr.h non-empty 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 patch. It's not clear why this file is part of the UAPI at all. Looking in: /usr/include/linux/irqnr.h 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 others): include/linux/irqnr.h:4:30: fatal error: uapi/linux/irqnr.h: No such file or directory Reported-by: Randy Dunlap <rdunlap@xenotime.net> Reported-by: Alessandro Suardi <alessandro.suardi@gmail.com> Signed-off-by: David Howells <dhowells@redhat.com> cc: Randy Dunlap <rdunlap@xenotime.net> cc: Alessandro Suardi <alessandro.suardi@gmail.com> 2012-10-17 11:31:15 +00:00			`/*`
