> {{XAttrStorage#updateINodeXAttrs}} modifies the inode's {{XAttrFeature}} based on reading
its current state.  However, the logic for reading current state is incorrect and may instead
read the state of the latest snapshot.  If xattrs have been changed after creation of that
snapshot, then subsequent xattr operations may yield incorrect results.
