Re: [fuse-devel] [PATCH V8 0/3] fuse: Add support for passthrough read/write

[Alessio Balsini]

Hi Antonio,

It's indeed a great idea to notify the FUSE daemon in case of lower file
system exceptions, otherwise transparent when passthrough is enabled.
I was already planning to work on this feature as a future extension, glad
to see that this is of interest to the community.

Thanks for your feedback,
Alessio
