Overlayfs TODOs

Quoted 4 lines · Chandan Rajendra

I am keen on working on overlayfs. It would be very helpful if you could provide me a list of Todo items associated with Overlayfs.

This is the TODO list that I maintain on wiki:
https://github.com/amir73il/overlayfs/wiki/Overlayfs-TODO

It includes at least most of the tasks that are in Miklos' head:
https://marc.info/?l=linux-unionfs&m=149441099931390&w=2

My focus right now is all the "non stared" tasks for "same fs" configuration, aiming for kernel 4.13.

Is there are specific area of interest for you with overlayfs? Any specific configuration or use case? Or is the interest purely academic?

I suppose you are looking to start of with smaller tasks?

There is actually one task that should be very simple to do and can also bring large benefit for many users.

In his pull request for kernel 4.12 Miklos writes:
"The biggest part of this is making st_dev/st_ino on the overlay behave like a normal filesystem ... future work will move the general case towards more sane behavior."

The work towards constant st_dev/st_ino for the general case is not within my immediate scope of interest, but it shouldn't be hard. The basic idea was explained by Miklos here:

Cheers,
Amir.
