Subject: [PATCH 1/2] Make sure the mount units pulled by 'RequiresMountsFor='
are loaded (if they exist)
We should make sure that mount units involved by 'RequiresMountsFor='
directives are really loaded if not required by any others units so
that Requires= dependencies on the mount units are applied and thus
the mount unit dependencies are started.
(cherry picked from commit 9b3757e9c8c8d6e161481193c4ef60e425a9ae41)

From d7f920bfcb0296fed214d4d3a21d64de09a68521 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/2] units: enable waiting for unit termination in certain
cases
The legacy cgroup hierarchy does not support reliable empty
notifications in containers and if there are left-over subgroups in a
cgroup. This makes it hard to correctly wait for them running empty, and
thus we previously disabled this logic entirely.
With this change we explicitly check for the container case, and whether
the unit is a "delegation" unit (i.e. one where programs may create
their own subgroups). If we are neither in a container, nor operating on
a delegation unit cgroup empty notifications become reliable and thus we
start waiting for the empty notifications again.
This doesn't really fix the general problem around cgroup notifications
but reduces the effect around it.
(This also reorders #include lines by their focus, as suggsted in
CODING_STYLE. We have to add "virt.h", so let's do that at the right
place.)
Also see #317.
(cherry picked from commit e9db43d5910717a1084924c512bf85e2b8265375)
