-Subject: [PATCH 095/134] printk: ringbuffer: Consider committed as finalized
- in panic
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
-
-A descriptor in the committed state means the record does not yet
-exist for the reader. However, for the panic CPU, committed
-records should be handled as finalized records since they contain
-message data in a consistent state and may contain additional
-hints as to the cause of the panic.
-
-Add an exception for records in the commit state to not be
-considered non-existing when reading from the panic CPU.
