Removing the blanket exposes eighteen items. Six are deleted; the rest belong to one feature that was never wired up. crates/ecstore/src/data_usage/local_snapshot.rs and its aggregation entry point, aggregate_local_snapshots, form a complete per-disk usage-snapshot feature: read/write of snapshot files under the metadata bucket, cross-disk aggregation, and tests. Nothing calls it. It landed in #5307 on 2026-07-27 and git log -S over the whole history shows the entry point has never had a caller; the live data-usage path is load_data_usage_from_backend / store_data_usage_in_backend. Rather than delete a recent, tested feature on cleanup grounds, the module gets a header explaining the situation and its items carry individual allows, so the gap stays greppable without reintroducing a blanket. One commit flips this to deletion if that is preferred. Deleted: - DATA_USAGE_BLOOM_NAME together with DATA_USAGE_BLOOM_NAME_PATH. Both are a dead duplicate of the pair in crates/scanner/src/data_usage_define.rs, which has roughly fifty consumers across scanner.rs and remote_scanner.rs; the ecstore copies have none. - increment_bucket_usage_memory and decrement_bucket_usage_memory, thin wrappers over the live record_bucket_object_write_memory and record_bucket_object_delete_memory. - sync_memory_cache_with_backend, whose doc comment says it is "called by scanner" — nothing calls it. - create_cache_entry_from_summary and cache_to_data_usage_info, neither with a consumer in any lane. resolve_loaded_snapshot is kept with an allow: nine tests in the same file assert its primary/backup fallback. Verification, four lanes warning-free: default, --tests, --features rio-v2 --tests, --features test-util --tests. rustfs-scanner still compiles clean. cargo nextest run -p rustfs-ecstore 4041 passed; clippy --lib --tests -D warnings clean; make pre-commit exit 0. Ref rustfs/backlog#1823 (step 2).
