Apparently tmpfs does not support generic xattr. I understand why
tmpfs is an attractive choice for an upper filesystem, so this should
be addressed.

I see two options here:

1) implement generic xattr in tmpfs
2) take whiteout/opaque support from union mounts and use that

Both have advantages and disadvantages.

Any thoughts?
