The linked commit reverts the change that accidentally used some sysfs enable/disable functions from Perf which broke the refcounting, but it also removes the fact that the sysfs disable function disabled the helpers. Add a new wrapper function that does both which is used by both Perf and sysfs, and label the sysfs disable function appropriately. The naming of all of the functions will be tidied up later to avoid this happening again.

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.
