[PATCH 02/27] selftests/landlock: Propagate EXPECT failures from forked children

[sashiko-bot at kernel.org]

> A failed ASSERT in a forked child calls abort(), so the parent sees
> the child die from a signal and the test fails.  A failed EXPECT only
> sets _metadata->exit_code, and a child that exits with a fixed status
> of 0 hides that failure from the parent.  The child in
> trace_fown.deny_scope_fown has this problem.
> 
> Exit with _metadata->exit_code in that child.  Do the same in the
> audit.log_subdomains_off_fork children.  They only use ASSERT for now,
> but this keeps them correct when a check becomes an EXPECT.
