When writing a tool for enabling events in the tracing system, an anomaly was discovered. The top level event "enable" file would never show "1" when all events were enabled. The system and event "enable" files worked as expected. The reason was because the top level event "enable" file included the "ftrace" tracer events, which are not controlled by the "enable" file and would cause the output to be wrong. This appears to have been a bug since it was created. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYCGOmxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qhDFAQDjSrHmSC0ziTck9QMXSUdxLs0gjENr R0n5WPZ/mRboxQD/aWlw99TnuSwFDzB0gTlwDuDd1Ge2snqqmFCRTscU7gE= =Pig3 -----END PGP SIGNATURE----- Merge tag 'trace-v5.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "Fix output of top level event tracing 'enable' file.

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.
