  * core: never propagate reload failure to service result.
    Fixes a regression introduced in v239 where the main process of a
    service unit gets killed on reload if ExecReload fails. (Closes: #936032)
  * shared/seccomp: add sync_file_range2.
    Some architectures need the arguments to be reordered because of alignment
    issues. Otherwise, it's the same as sync_file_range.
    Fixes sync_file_range failures in nspawn containers on arm, ppc.
    (Closes: #935091)
  * core: factor root_directory application out of apply_working_directory.
    Fixes RootDirectory not working when used in combination with User.
    (Closes: #939408)
  * shared/bus-util: drop trusted annotation from
    bus_open_system_watch_bind_with_description().
    This ensures that access controls on systemd-resolved's D-Bus interface
    are enforced properly.
    (CVE-2019-15718, Closes: #939353)
  * login: add a missing error check for session_set_leader()
    Fixes assertion due to insufficient function return check.
    (Closes: #939998)
  * d/e/r/73-usb-net-by-mac.rules: import net.ifnames only for network devices
    (Closes: #934589)
  * d/e/r/73-usb-net-by-mac.rules: skip if iface name was provided by user-space
  * namespace: make MountFlags=shared work again (Closes: #939551)
  * mount/generators: do not make unit wanted by its device unit.
    Among other things, this fixes StopWhenUnneeded=true being broken for
    mount units. (Closes: #941758)
