From f210735fe2f17a6225432ee3d1239bcf23a8659c Mon Sep 17 00:00:00 2001 From: Markus Trippelsdorf Date: Fri, 24 Jun 2011 15:51:00 +0200 Subject: headers_install: fix __packed in exported kernel headers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit checkpatch.pl warns about using __attribute__((packed)) in kernel headers: "__packed is preferred over __attribute__((packed))". If one follows that advice it could cause problems in the exported header files, because the outside world doesn't know about this shortcut. For example busybox will fail to compile: CC miscutils/ubi_attach_detach.o In file included from miscutils/ubi_attach_detach.c:27:0: /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’ /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here ... Fix the problem by substituting __packed with __attribute__((packed)) in the header_install.pl script.
