I think this should be
if (!(current->flags & PF_NOFREEZE))
debug_check_no_locks_held(...);
without "return". This way we avoid the unnecessary PF_NOFREEZE check
if !CONFIG_LOCKDEP. And perhaps more importantly, this way it is clear
that we check PF_NOFREEZE for debugging only and do not change the code
behaviour.
But I leave this to Rafael/Tejun.
And again, unless I missed something, this makes 1/5 unnecessary.
