i was just working on the v2 and I saw :
"@release: pointer to the function that will clean up the object when the
last reference to the object is released. This pointer is required, and
it is not acceptable to pass kfree in as this function.  If the caller
does pass kfree to this function, you will be publicly mocked mercilessly
by the kref maintainer".

so i thought of checking and it looks like there are a few instances
where kref has been passed as release.  :)
