[PATCH v3 0/2] Handle notifications on overlayfs fake path files

[Amir Goldstein <amir73il@gmail.com>]

Miklos,

Third attempt with the eye towards simplifying d_real() interface.

Like v2, most of the vfs code should remain unaffected by this
expect for the special fsnotify case that we wanted to fix.

Thanks,
Amir.

Changes since v2:
- Restore the file_fake container (Miklos)
- Re-arrange the v1 helpers (Christian)

Changes since v1:
- Drop the file_fake container
- Leave f_path fake and special case only fsnotify

Amir Goldstein (2):
  fs: use fake_file container for internal files with fake f_path
  ovl: enable fsnotify events on underlying real files
