We can convert this file to using export.h since it only wants to export symbols, but when we do we'll see also that it was implicitly getting notifier.h from module.h via this failure: CC arch/powerpc/platforms/cell/spu_notify.o arch/powerpc/platforms/cell/spu_notify.c:28: warning: type defaults to 'int' in declaration of 'BLOCKING_NOTIFIER_HEAD' arch/powerpc/platforms/cell/spu_notify.c:28: warning: parameter names (without types) in function declaration arch/powerpc/platforms/cell/spu_notify.c: In function 'spu_switch_notify': arch/powerpc/platforms/cell/spu_notify.c:32: error: implicit declaration of function 'blocking_notifier_call_chain' arch/powerpc/platforms/cell/spu_notify.c:32: error: 'spu_switch_notifier' undeclared (first use in this function) Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
