An output message: > # # waitpid WEXITSTATUS=0 will be printed for 30,000+ times in the `pidfd_test` selftest, which does not seem ideal. This patch removes the print logic in the `wait_for_pid` function, so each call to this function does not output a line by default. Any existing call sites where the extra line might be beneficial have been modified to include extra print statements outside of the function calls.

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.
