This series fixes two issues in the local backend when using the mapped-file
security mode:
- allow chmod and chown to succeed on the virtfs root (patch 4)
- completely hide the metadata files from the client (patch 5)
Patch 2 resolves '.' and '..' in paths, and patch 3 reworks the way we open
files accordingly. They could be squashed together in a single patch (this
was the case in earlier versions actually), but I decided to separate them
for easier review.
Léo,
I'd appreciate if you could test this series (especially patch 4) on your
setup.
Cheers.
