From f440d909085e497540788fecc056dc39ea0471ed Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 2 Feb 2017 12:26:51 +0100 Subject: [PATCH] staging: lustre: remove CLASSERT macro lustre uses a fake switch() statement as a compile-time assert, but unfortunately each use of that causes a warning when building with clang: drivers/staging/lustre/lnet/klnds/socklnd/socklnd.c:2907:2: warning: no case matching constant switch condition '42' drivers/staging/lustre/lnet/klnds/socklnd/../../../include/linux/libcfs/libcfs_private.h:294:36: note: expanded from macro 'CLASSERT' #define CLASSERT(cond) do {switch (42) {case (cond): case 0: break; } } while (0) As Greg suggested, let's just kill off this macro completely instead of fixing it. This replaces it with BUILD_BUG_ON(), which means we have to negate all the conditions in the process.
