It may lead to kernel panic when execute the following testcase on mips: # cd tools/testing/selftests/ftrace # ./ftracetest test.d/kprobe/multiple_kprobes.tc A preliminary analysis shows that the issue is related with echo 1 > events/kprobes/enable after add the 256 probe points. In order to find the root cause, I want to verify which probe point has problem, so it is necessary to save kprobe_events to test log. With this patch, we can get the 256 probe points in the test log through the following command: # ./ftracetest test.d/kprobe/multiple_kprobes.tc -vvv -k Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Acked-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
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.
