Dump the remaining PERF_SAMPLE_ data, as if it is dumping a direct sample. Put the stack trace, tid, off-cpu time and cgroup id into the raw_data section, just like a direct off-cpu sample coming from BPF's bpf_perf_event_output(). This ensures that evsel__parse_sample() correctly parses both direct samples and accumulated samples.

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.
