Kprobes bypasses our debug hook registration code so that it doesn't get tangled up with recursive debug exceptions from things like lockdep: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/324385.html However, since then, (a) the hook list has become RCU protected and (b) the kprobes hooks were found not to filter out exceptions from userspace correctly. On top of that, the step handler is invoked directly from single_step_handler(), which *does* use the debug hook list, so it's clearly not the end of the world. For now, have kprobes use the debug hook registration API like everybody else. We can revisit this in the future if this is found to limit coverage significantly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
