Subject: [PATCH 25/54] printk: Flush nbcon consoles first on panic
|
||
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.11/older/patches-6.11-rt7.tar.xz
|
||
|
|
|
||
|
|
In console_flush_on_panic(), flush the nbcon consoles before
|
||
|
|
flushing legacy consoles. The legacy write() callbacks are not
|
||
|
|
fully safe when oops_in_progress is set.
