From 4cb3ca7cd7e2cae8d1daf5345ec99a1e8502cf3f Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Mon, 19 Apr 2010 23:53:06 +0200 Subject: [PATCH] UML: Fix compiler warning due to missing task_struct declaration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We can't pull in linux/sched.h due to circular dependency, so just forward-declare the struct. This fixes the following warning: CC arch/um/sys-i386/elfcore.o In file included from /data/linux-2.6/include/linux/elf.h:8, from /data/linux-2.6/arch/um/sys-i386/elfcore.c:2: arch/um/sys-i386/asm/elf.h:78: warning: ‘struct task_struct’ declared inside parameter list arch/um/sys-i386/asm/elf.h:78: warning: its scope is only this definition or declaration, which is probably not what you want I guess not many people build against i386 hosts anymore, so this remained widely unnoticed.
