snprintf returns the actual length of the buffer created; however, this is not the case if snprintf truncates its parameter. See https://lwn.net/Articles/69419/ for a detailed explanation. The current code correctly handles this case at the expense of extra code in the return statement. scnprintf does returns the actual length of the buffer created making the ?: operator unnecessary in the return statement. This change does not alter the functionality of the code. Signed-off-by: Daniel M German <dmg@turingmachine.org> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
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.
