- PutObjectMetadata() - PutObjectTags() - DeleteObjectTags() - TransitionObject() - RestoreTransitionObject() Also improve the behavior of multipart code across pool locks, hold locks only once per upload ID for - CompleteMultipartUpload() - AbortMultipartUpload() - ListObjectParts() (read-lock) - GetMultipartInfo() (read-lock) - PutObjectPart() (read-lock) This avoids lock attempts across pools for no reason, this increases O(n) when there are n-pools.
