You could perhaps, for accounting purposes, elevate a portion of the allocation from revocable
to non-revocable.

The reason I do not add a helper function because even though the code are almost same, there
are indeed difference between logs, `updateAllocation` will have some logs related to `framework`
and `agent`, `updateAvailable` will only have some logs related to `agent`. I prefer that
we keep the changes separtely to make log message clear for different cases, comments? Thanks.
