* Memory protection directives can now take a value of zero, allowing
explicit opting out of a default value propagated by an ancestor.
- * A new setting DisableControllers= has been added that may be used to
- explicitly disable one or more cgroups controllers for a unit and all
- its children.
-
* systemd now defaults to the "unified" cgroup hierarchy setup during
build-time, i.e. -Ddefault-hierarchy=unified is now the build-time
default. Previously, -Ddefault-hierarchy=hybrid was the default. This
option that permits selecting the timout how long to wait for a
device with an encryption key before asking for the password.
+ * IOWeight= has learnt to properly set the IO weight when using the
+ BFQ scheduler officially found in kernels 5.0+.
