The tracing_set_trace_write() function just removes the trailing whitespace from the user supplied tracer name, but the leading whitespace should also be removed. In addition, if the user supplied tracer name contains only a few whitespace characters, the first one will not be removed using the current method, which results it a single whitespace character left in the buf. To fix all of these issues, we use strim() to correctly remove both the leading and trailing whitespace.

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.
