It's a const tradeoff :)

listxattr also need check option_.fileSystemOption.disableXAttr

Is it possible to use FuseContext as a variable instead of creating a new one every time?

No, because we should get the latest uid and gid which can modified on fly.

why wrap it?

why wrap it?

In order to:

Form a unified namespace, like you can find all string related function in strings namespace.

One header include all util functions: you can find all functions once you include the utils.h header file and if you use absl library, you should find the function in which header and include it.

It is more easy to use.
