With procfs v3.3.16, the sysctl command doesn't print the set key and value on error. This change breaks livepatch selftest test-ftrace.sh, that tests the interaction of sysctl ftrace_enabled: Make it work with all sysctl versions using '-q' option. Explicitly print the final status on success so that it can be verified in the log. The error message is enough on failure.

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.
