5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: NeilBrown <neilb@xxxxxxx>
[ Upstream commit cf0e124e0a489944d08fcc3c694d2b234d2cc658 ]
These definitions are not used outside of svc.c, and there is no
evidence that they ever have been. So move them into svc.c
and make the declarations 'static'.
