[RFC 0/2] refcount: attempt to avoid imbalance warnings

Hi,

This patch tries to avoid some sparse warnings related to
refcount_dec_and_lock() and kref_put_lock().

I send this patch series as RFC because it was necessary to do a kref
change after adding __cond_lock() to refcount_dec_and_lock()
functionality.

For me it looks like we do a lot of acrobatics to avoid sparse warnings
here and I really don't know if it's worth the offer. However this is
what I have now...

refcount: add __cond_lock() for conditional lock refcount API
kref: move kref_put_lock() callback to caller
