Compiles debug level messages into the kernel, which would not
|
||||
otherwise be available at runtime. These messages can then be
|
||||
enabled/disabled based on various levels of scope - per source file,
|
||||
function, module, format string, and line number. This mechanism
|
||||
implicitly compiles in all pr_debug() and dev_dbg() calls, which
|
||||
enlarges the kernel text size by about 2%.
