Writeback_cache support

[DaRacci]

Looking into fuse 3, there is supposed to be a good performance improvement from using the writeback_cache mode is this something that can already be passed through to the fuse options in some way?

I've tried with -o writeback_cache but it wasn't recognised.

No, supporting it correctly requires some small code changes. That's probably why libfuse doesn't make the option available by default.
