From 6a09d17bb66a533c165be81e8a4c3557f68e1a3b Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 18 Jul 2014 18:56:34 +0100 Subject: KEYS: Provide a generic instantiation function Provide a generic instantiation function for key types that use the preparse hook. This makes it easier to prereserve key quota before keyrings get locked to retain the new key.
