selftests: add pid namespace ENOMEM regression test2020-03-25T12:50:34+00:00Christian Braunerchristian.brauner@ubuntu.com2020-03-08T16:26:32+00:00urn:sha1:6952a4f646446fde9e190b62c5e45f84c6cf91aa
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.
