-Subject: [PATCH 097/134] printk: Avoid non-panic CPUs writing to ringbuffer
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
-
-Commit 13fb0f74d702 ("printk: Avoid livelock with heavy printk
-during panic") introduced a mechanism to silence non-panic CPUs
-if too many messages are being dropped. Aside from trying to
-workaround the livelock bugs of legacy consoles, it was also
-intended to avoid losing panic messages. However, if non-panic
-CPUs are writing to the ringbuffer, then reacting to dropped
-messages is too late.
-
-To avoid losing panic CPU messages, silence non-panic CPUs
-immediately on panic.
