Allow implementations to support a custom comparison function.

would it be okay to check if fs.Stat('/') == fs2.Stat('/') as a way of seeing if they're the same filesystem?

[willscott]

would 828ed72 be sufficient? - i guess maybe would also be worthwhile to compare that the billy.Capabilities() of the two filesystems are the same

[DUOLabs333]

Now I get comparing uncomparable type main.OverlayStat (this is because in order to fix some inode validation issue with my implementation, I have to add the filesystem as an attribute).

[willscott]

I'm okay doing this with c33eb6b

[DUOLabs333]

Can we use DeepEqual on fs and fs2 directly? Alternatively, I was thinking that we can compare the pointer values of the two filesystems.

yes, that was my intention of what I was showing - the commit diff is confusing. https://github.com/willscott/go-nfs/compare/fix/onrename-fs is better

[DUOLabs333]

Ok, with the commit, Rename no longer crashes (it doesn't look like it returns the wrong thing).
