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.
25 Kernel components (e.g. device drivers) can register themselves at the debug
28 debug log for the caller. For each debug log exists a number of debug areas
29 where exactly one is active at one time. Each debug area consists of contiguous
