The "perf record" tool will now default to this new mode if the user specifies a sampling group when not in system-wide mode, and when "--no-inherit" is not specified. This change updates evsel to allow the combination of inherit and PERF_SAMPLE_READ. A fallback is implemented for kernel versions where this feature is not supported.

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.
