[pve-devel] [PATCH container] mountpoint mount: activate PVE-managed volumes during preparation

[Fiona Ebner <f.ebner@proxmox.com>]

Otherwise it was not possible to hotplug a volume that was previously
deactivated and requires activation, e.g. an LVM LV that was detached
after shutting down the container couldn't be hotplugged anymore
later.

Requires the following patch to be tested on recent kernels:
