Description Michael Gmelin freebsd_committer 2021-08-02 10:08:45 UTC
When listing POSIX shared memory segments using posixshmcontrol, it
would be nice to be able to limit the output based on jail id and/or
jail name, e.g.

    posixshmcontrol -j shmtest ls

This could be made work based on the jail's path, as this already
controls access to shared memory segments (and should also
work subjails/jail hierarchies - hence the dependency on bug #257554).
