      StorageEngine::flushAllFiles() takes a boolean parameter, sync, which performs synchronous flushing when true and asynchronous flushing when false. However,

      • MMAPv1 on Windows cannot support asynchronous flushing, and using MS_ASYNC in Posix is a no-op (see SERVER-22271).
      • WiredTiger and the other KVEngine-based storage engines all ignore the sync parameter, doing the flush synchronously.
      • RocksDB also ignores the sync parameter.

      As a consequence, there is no longer a need to keep the sync parameter.
