I have a report of divide error on 4.11.5-200.fc25.x86_64:

	https://bugzilla.kernel.org/show_bug.cgi?id=196235

It looks like

	df807fffaabd "NFSv4.x/callback: Create the callback service
		through svc_create_pooled"

should have had a stable cc.

I believe it's needed on any kernel containing bb6aeba736ba "NFSv4.x:
Switch to using svc_set_num_threads() to manage the callback threads"
(which went in to 4.9).

--b.
