Subject: [PATCH v7 01/25] kexec: quiet down kexec reboot
Date: Wed, 16 Oct 2019 16:00:10 -0400 [thread overview]
Message-ID: <20191016200034.1342308-2-pasha.tatashin@soleen.com> (raw)
In-Reply-To: <20191016200034.1342308-1-pasha.tatashin@soleen.com>
Here is a regular kexec command sequence and output:
=====
$ kexec --reuse-cmdline -i --load Image
$ kexec -e
[ 161.342002] kexec_core: Starting new kernel
Welcome to Buildroot
buildroot login:
=====
Even when "quiet" kernel parameter is specified, "kexec_core: Starting
new kernel" is printed.
This message has KERN_EMERG level, but there is no emergency, it is a
normal kexec operation, so quiet it down to appropriate KERN_NOTICE.
Machines that have slow console baud rate benefit from less output.
