My first thought on this was that I prefer the explicitness
of pairing __free(kfree) with no_free_ptr as was done here.

cleanup.h defines this: 
#define return_ptr(p)   return no_free_ptr(p)

I did read the comments and am still confused. I see you posted a
handful of no_free_ptr to return_ptr patches. What is your selection
process for changing these?
