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.
|
||||
|
||||

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.
|
||||
|
||||
