GDB Tracepoints for the Linux Kernel

[Jim Blandy]

At FOSDEM 2007 last weekend, I gave a presentation on a Linux loadable
kernel module and some GDB patches that allow you to use GDB to debug
the kernel it's running under.  In the demo, people liked it when
Emacs popped up the source code for vfs_write.  :)

Slides and a tarball containing code and patches are available from
http://www.red-bean.com/trac/tracepoints.  The tarball's README file
has instructions for getting things going.
