From 903c0c7cdc21f2ccb7562a7bbc70289c0c2b16ad Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro Date: Tue, 24 May 2011 17:13:16 -0700 Subject: sparse: define dummy BUILD_BUG_ON definition for sparse BUILD_BUG_ON() causes a syntax error to detect coding errors. So it causes sparse to detect an error too. This reduces sparse's usefulness. This patch makes a dummy BUILD_BUG_ON() definition for sparse.
