-<p class="Pp">The debug file system, or debugfs, makes process debugging easier
- by providing a simple API for data transfer between the kernel and user
- space. Debugfs is not a general-purpose file system and should not be used
- as a storage medium. Instead, developers can implement the debugfs interface
- in their code to generate debug information about their program at runtime.
- FreeBSD's <code class="Nm">lindebugfs</code> uses the
- <a class="Xr">pseudofs(9)</a> file system construction kit to model itself
- after Linux's debugfs. The <code class="Nm">lindebugfs</code> API is
- intended for use with programs that take advantage of FreeBSD's LinuxKPI
- compatibility layer.</p>
-<p class="Pp">When mounted, <code class="Nm">lindebugfs</code> will populate
- with pseudo files from any running process that calls
- <code class="Nm">debugfs_create_file()</code>. Since
- <code class="Nm">lindebugfs</code> is a pseudo file system, file contents
- will be generated dynamically based on program provided file operations. The
- current <code class="Nm">lindebugfs</code> implementation formally supports
- seq_file and simple_attr_file virtual file formats.</p>
