[PATCH 15/27] selftests/landlock: Close leaked file descriptors

[sashiko-bot at kernel.org]

> Several tests do not close file descriptors they open: the /dev/null FD
> in restrict_self_fd and restrict_self_fd_flags, and the parent's ends
> of the synchronization pipes in various ptrace, audit, signal and
> abstract UNIX socket tests.
> 
> Close them once they are not needed anymore.
