*	locking/refcounts: Change WARN() to WARN_ONCE()	Ingo Molnar	2017-03-01	1	-7/+7
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Linus noticed that the new refcount.h APIs used WARN(), which would turn into a dmesg DoS if it triggers frequently on some buggy driver. So make sure we only warn once. These warnings are never supposed to happen, so it's typically not a problem to lose subsequent warnings.

*	locking/refcounts: Out-of-line everything	Peter Zijlstra	2017-02-24	1	-0/+267
	Linus asked to please make this real C code. And since size then isn't an issue what so ever anymore, remove the debug knob and make all WARN()s unconditional.
