Linux kernel source tree

When generating a string for sample flags, the sample_flags_to_name() function lacks the ability to parse the trace start bit or trace end bit. Therefore, the function is invoked multiple times after clearing its unsupported bits. This commit improves the sample_flags_to_name() function to parse sample flags in one go for three kinds of information: - The prefix info for trace start, trace end, etc. - Branch types. - Extra info for transaction and interrupt related info. As a result, the code is simplified to call the sample_flags_to_name() only once. No expectation for any changes in the perf script output.

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.
