# modprobe trace-events-sample
# echo 1 > /sys/kernel/debug/tracing/events/sample-trace/enable
# rmmod trace-events-sample
This would cause an oops. The issue is that I added another trace
event sample that reused a reg function of another trace event to
create a thread to call the tracepoints. The problem was that the
reg function couldn't handle nested calls (reg; reg; unreg; unreg;)
and created two threads (instead of one) and only removed one
on exit.
This isn't a critical bug as the bug is only in sample code. But sample
code should be free of known bugs to prevent others from copying
it. This is why this is also marked for stable.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
