You'll need to wrap them in: #ifndef __clang__ preprocessor macros, or I think we have a pragma helper in tree that helps with compiler specific pragmas. IIRC it uses _Pragma to define pragmas in macros. > In file included from drivers/scsi/qla2xxx/qla_dbg.c:77: > In file included from include/trace/events/qla.h:44: > In file included from
