Miklos, As discussed, here are the patches for the new mount options. - Only string format is supported - Legacy lowerdir= cannot be mixed with new lowerdir+,datadir+ - lowerdir+,datadir+ are not escaped - lowerdir,upperdir,workdir are escaped as always I did not find a good reason to change escaping of upperdir,workdir. We can skip escaping when we add support for path format. Wrote some xfstests [1]. Thanks, Amir.
