As Linus pointed out [1], lockref_put_return() is fundamentally
designed to be something that can fail. It behaves as a fastpath-only
thing, and the failure case needs to be handled anyway.
Actually, since the new pcluster was just allocated without being
populated, it won't be accessed by others until it is inserted into
XArray, so lockref helpers are actually unneeded here.
Let's just set the proper reference count on initializing.
From a quick superficial look this looks like the right approach.
Thanks for the quick response.
