-Subject: [PATCH 28/50] printk: nbcon: Add unsafe flushing on panic
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.7/older/patches-6.7-rt6.tar.xz
-
-Add nbcon_atomic_flush_unsafe() to flush all nbcon consoles
-using the write_atomic() callback and allowing unsafe hostile
-takeovers. Call this at the end of panic() as a final attempt
-to flush any pending messages.
-
-Note that legacy consoles use unsafe methods for flushing
-from the beginning of panic (see bust_spinlocks()). Therefore,
-systems using both legacy and nbcon consoles may still fail to
-see panic messages due to unsafe legacy console usage.
