This set of build failures just started appearing on parisc: In file included from drivers/input/serio/serio_raw.c:12: include/linux/kref.h: In function 'kref_get': include/linux/kref.h:40: error: 'TAINT_WARN' undeclared (first use in this function) include/linux/kref.h:40: error: (Each undeclared identifier is reported only once include/linux/kref.h:40: error: for each function it appears in.) include/linux/kref.h: In function 'kref_sub': include/linux/kref.h:65: error: 'TAINT_WARN' undeclared (first use in this function) It happens because TAINT_WARN is defined in kernel.h and this particular compile doesn't seem to include it (no idea why it's just manifesting ... probably some #include file untangling exposed it). Fix by adding #include <linux/kernel.h> to linux/kref.h Signed-off-by: James Bottomley <JBottomley@xxxxxxxxxxxxx> --- diff --git a/include/linux/kref.h b/include/linux/kref.h index abc0120..9c07dce 100644 --- a/include/linux/kref.h +++ b/include/linux/kref.h @@ -17,6 +17,7 @@ #include <linux/bug.h> #include <linux/atomic.h> +#include <linux/kernel.h> struct kref { atomic_t refcount; ��.n��������+%������w��{.n�����{�������{ay�ʇڙ���f���h������_�(�階�ݢj"��������G����?���&��
