> Reservations that belong to a role that has no quota may not be allocated
> even when the reserved resources are allocatable to the role.
> This is because in the current implementation the reserved resources may be
> counted towards the headroom left for unallocated quota limit in the second
> stage allocation.

> Roles with quota do not have this issue because currently their reservations
> are taken care of in the first stage.
