The traceevent lib is used by the perf tool, and when executing perf test -v 6 it outputs error log on the ARM64 platform: running test 33 '*:*'trace-cmd: No such file or directory [...] trace-cmd: Invalid argument The trace event parsing code originally came from trace-cmd so it keeps the tag string "trace-cmd" for errors, this easily introduces the impression that the perf tool launches trace-cmd command for trace event parsing, but in fact the related parsing is accomplished by the traceevent lib. This patch changes the tag string to "libtraceevent" so that we can avoid confusion and let users to more easily connect the error with traceevent lib.

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.
