sf_disable() returns the condition code of instruction lsctl (load sampling controls). However the parameter to lsctl() in sf_disable() is a sample control block containing all zeroes. This invocation of lsctl() does not fail and returns always zero even when there is no authorization for sampling on the machine. In short, sampling can be always turned off. Ignore the return code of sf_disable() and change the function return to void.

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 reStructuredText 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.
