-Subject: [PATCH 1/2] printk: add support for lockless ringbuffer
-
-Linux 5.10 introduces a new lockless ringbuffer. The new ringbuffer
-is structured completely different to the previous iterations.
-Add support for dumping the ringbuffer with the "log" command.
-The new ringbuffer is detected based on the availability of
-the "prb" symbol.
-
-Upstream-Status: Backport [https://github.com/crash-utility/crash/commit/a5531b24750e7949c35640d996ea14c0587938bc]

-An addendum to the previous crash commit a5531b24750e.
-The ringbuffer entries use 2 state values (committed and finalized)
-rather than a single flag to represent being available for reading.
-Copy the definitions and state lookup function directly from the
-kernel source and use the new states.
-
-Upstream-Status: Backport [https://github.com/crash-utility/crash/commit/71e159c64000467e94e08aefc144f5e1cdaa4aa0]
