From 9d77eb52778499a97cab662aa96de4e2e4fa72d3 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Thu, 24 Aug 2023 16:39:08 +0200 Subject: nvme-keyring: register '.nvme' keyring Register a '.nvme' keyring to hold keys for TLS and DH-HMAC-CHAP and add a new config option NVME_KEYRING. We need a separate keyring for NVMe as the configuration is done via individual commands (eg for configfs), and the usual per-session or per-process keyrings can't be used.
