    selftests: add pid namespace ENOMEM regression test · 6952a4f6
    Christian Brauner authored
    We recently regressed (cf. [1] and its corresponding fix in [2]) returning
    ENOMEM when trying to create a process in a pid namespace whose init
    process/child subreaper has already died. This has caused confusion at
    least once before that (cf. [3]). Let's add a simple regression test to
    catch this in the future.
