Just imagine how debugfs works. It has probes over the code where *_dbg/debug() prints are used. Those special data structures are kept in the specific part of the file / kernel. If there is no module, how will kernel know that there is a portion of such data there? -- With Best Regards, Andy Shevchenko -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
