+Subject: [PATCH 083/323] printk: kmsg_dump: remove unused fields
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+struct kmsg_dumper still contains some fields that were used to
+iterate the old ringbuffer. They are no longer used. Remove them
+and update the struct documentation.
