[pve-devel] [PATCH v2 storage 2/7] dir plugin: get notes: return undef if notes are not supported

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

This avoids showing empty notes in the result of the content/{volid}
API call for volumes that do not even support notes. It's also in
preparation for the proposed get_volume_attribute generalization,
which expects undef to be returned when an attribute is not supported.

New in v2.
