I have made some changes following suggestion by Americo Wang advise, to the following: (patch by Ingo) diff --git a/kernel/lockdep_internals.h b/kernel/lockdep_internals.h index 699a2ac..031f4c6 100644 --- a/kernel/lockdep_internals.h +++ b/kernel/lockdep_internals.h @@ -65,7 +65,7 @@ enum { * Stack-trace: tightly packed array of stack backtrace * addresses.

This is being discussed in detail in another message exchange on the lkml, between me and Americo.
