Description

Looking in the Linux source code, we see the following:

http://lxr.linux.no/linux+v3.14.3/fs/xattr.c

  60        /*
  61         * In the user.* namespace, only regular files and directories can have
  62         * extended attributes. For sticky directories, only the owner and
  63         * privileged users can write attributes.
  64         */

We should consider removing XAttrFeature from INodeSymlink.
