11 The goal of this feature is to provide a kernel debug logging API
13 (e.g. device drivers) can have one separate debug log.
14 One purpose of this is to inspect the debug logs after a production system crash
18 it is possible to look at the debug logs on a live system via the Linux
21 The debug feature may also very useful for kernel and driver development.
