Subject: [PATCH v2 5/7] kexec_file, ricv: print out debugging message if required
Date: Fri, 24 Nov 2023 11:36:40 +0800 [thread overview]
Message-ID: <20231124033642.520686-6-bhe@redhat.com> (raw)
In-Reply-To: <20231124033642.520686-1-bhe@redhat.com>
Replace pr_debug() with the newly added kexec_dprintk() in kexec_file
loading related codes.
And also remove kexec_image_info() because the content has been printed
out in generic code.
