The files in the procfs are there to - allow userland programs access to certain information from the - kernel (like process information in <filename - class="directory">/proc/[0-9]+/</filename>), but also for debug - purposes (like <filename>/proc/ksyms</filename>). - </para> - - <para> - This guide describes the use of the procfs file system from - within the Linux kernel.
