selftests: add tests for pidfd_send_signal() As suggested by Andrew Morton in [1] add selftests for the new sys_pidfd_send_signal() syscall: /* test_pidfd_send_signal_syscall_support / Test whether the pidfd_send_signal() syscall is supported and the tests can be run or need to be skipped. / test_pidfd_send_signal_simple_success / Test whether sending a signal via a pidfd works. / test_pidfd_send_signal_exited_fail / Verify that sending a signal to an already exited process fails with ESRCH. / test_pidfd_send_signal_recycled_pid_fail */ Verify that a recycled pid cannot be signaled via a pidfd referring to an already exited process that had the same pid (cf. [2], [3]).
