[PATCH v2 0/3] Handle notifications on overlayfs fake path files

[Amir Goldstein <amir73il@gmail.com>]

Miklos,

The first solution that we discussed for removing FMODE_NONOTIFY
from overlayfs real files using file_fake container got complicated.

This alternative solution is less intrusive to vfs and all the vfs
code should remian unaffected expect for the special fsnotify case
that we want to fix.

Thanks,
Amir.

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