No. Overlayfs doesn't support network filesystems as modifiable (upper) layer, and that's where atomic_open makes sense. I think actually no filesystem that defines atomic_open() can be used as upper layer. So that's currently not a worry. If it turns out to be a requirement to use such filesystem as upper, then I'll worry about atomic_open().
