From 1ed97629adffa6b5345963ec8905526da835535a Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sat, 20 Feb 2010 23:22:54 +0100 Subject: remove libosmocore from openbsc From now on, you will have to obtain, build and install libosmocore before being able to build openbsc. Sorry for that. But I hope it's a small price to pay for having no code duplication with our work on the phone side GSM stack! --- libosmocore/include/osmocore/linuxlist.h | 360 ------------------------------- 1 file changed, 360 deletions(-) delete mode 100644 libosmocore/include/osmocore/linuxlist.h (limited to 'libosmocore/include/osmocore/linuxlist.h') diff --git a/libosmocore/include/osmocore/linuxlist.h b/libosmocore/include/osmocore/linuxlist.h deleted file mode 100644 index fb99c5ec8..000000000 --- a/libosmocore/include/osmocore/linuxlist.h +++ /dev/null @@ -1,360 +0,0 @@ -#ifndef _LINUX_LLIST_H -#define _LINUX_LLIST_H - -#include - -#ifndef inline -#define inline __inline__ -#endif - -static inline void prefetch(const void *x) {;} - -/** - * container_of - cast a member of a structure out to the containing structure - * - * @ptr: the pointer to the member. - * @type: the type of the container struct this is embedded in. - * @member: the name of the member within the struct. - * - */ -#define container_of(ptr, type, member) ({ \ - const typeof( ((type *)0)->member ) *__mptr = (typeof( ((type *)0)->member ) *)(ptr);
