File nvme_call_home-remove-d-and-f-as-visible-options.patch of Package ppc64-diag
From 11cb2a44a59b63bdc23c94e386c4e2f43ea7eb61 Mon Sep 17 00:00:00 2001 From: Greg Joyce <gjoyce@linux.vnet.ibm.com> Date: Fri, 22 Sep 2023 15:19:34 -0500 Subject: [PATCH] nvme_call_home: remove -d and -f as visible options The dump(-d) and file(-f) options have been removed as option in usage and also in the man page. The options are for internal test only and should not have been exposed. Also added some helpful status messages.
