The service's prevActiveBackendCount denotes the count of previously active backend entries that were added to the BPF map so that the function can remove obsolete ones.

The service's non-active backends are appended to the active backends list, and skipped from the service backends count set in the master key so that the non-active backends will not be considered for load-balancing traffic. The backends count is used in the datapath to determine if a service has any backends. The non-active backends are, however, populated in the service map so that they can be restored upon agent restart along with their state.
