From 45b35a5ced474b9fbbbfcfd5cf346c432d28d9fd Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Thu, 8 Jun 2006 00:43:41 -0700 Subject: [PATCH] [PATCH] Fix mempolicy.h build error MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit From: Ralf Baechle uses struct mm_struct and relies on a definition or declaration somehow magically being dragged in which may result in a build: [...] CC mm/mempolicy.o In file included from mm/mempolicy.c:69: include/linux/mempolicy.h:150: warning: ‘struct mm_struct’ declared inside parameter list include/linux/mempolicy.h:150: warning: its scope is only this definition or declaration, which is probably not what you want include/linux/mempolicy.h:175: warning: ‘struct mm_struct’ declared inside parameter list mm/mempolicy.c:622: error: conflicting types for ‘do_migrate_pages’ include/linux/mempolicy.h:175: error: previous declaration of ‘do_migrate_pages’ was here mm/mempolicy.c:1661: error: conflicting types for ‘mpol_rebind_mm’ include/linux/mempolicy.h:150: error: previous declaration of ‘mpol_rebind_mm’ was here make[1]: *** [mm/mempolicy.o] Error 1 make: *** [mm] Error 2 [ralf@denk linux-ip35]$ Including is a step into direction of include hell so fixed by adding a forward declaration of struct mm_struct instead.
