The following commit has been merged in the next branch: commit 46e1b7ca0e55f55e81c227d82eef3d1dc77ad5ae Author: Sven Eckelmann sven@narfation.org Date: Sat Jan 15 14:39:43 2011 +0000
batman-adv: Use "__attribute__" shortcut macros
Linux 2.6.21 defines different macros for __attribute__ which are also used inside batman-adv. The next version of checkpatch.pl warns about the usage of __attribute__((packed))).
Linux 2.6.33 defines an extra macro __always_unused which is used to assist source code analyzers and can be used to removed the last existing __attribute__ inside the source code.
