selftests: add pid namespace ENOMEM regression testWe recently regressed (cf. [1] and its corresponding fix in [2]) returningENOMEM when trying to create a process in a pid namespace whose initprocess/child subreaper has already died. This has caused confusion atleast once before that (cf. [3]). Let's add a simple regression test tocatch this in the future.[1]: 49cb2fc42ce4 ("fork: extend clone3() to support setting a PID")[2]: b26ebfe12f34 ("pid: Fix error return value in some cases")[3]: 35f71bc0a09a ("fork: report pid reservation failure properly")Cc: Corey Minyard Cc: Oleg Nesterov Cc: Adrian Reber Cc: Dmitry Safonov <0x7f454c46@gmail.com>Cc: Andrei Vagin Signed-off-by: Christian Brauner List of files: /linux-6.15/tools/testing/selftests/pid_namespace/config
