From 9d9cf8de8b2ad8273861a30476a46f34cd34871a Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Tue, 14 Nov 2023 23:20:30 +0800 Subject: [PATCH] kexec_file: add kexec_file flag to support debug printing Content-type: text/plain This add KEXEC_FILE_DEBUG to kexec_file_flags so that it can be passed to kernel when '-d' is added with kexec_file_load interface. With that flag enabled, kernel can enable the debugging message printing.
