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.
