* [pve-devel] [PATCH proxmox-fuse-rs] add explicit "C" ABI to all extern function declarations

To: pve-devel
This fixes deprecation warnings where extern function declarations
did not explicitly specify the ABI. All extern fn types in the
FUSE Operations struct now use `extern "C" fn` instead of `extern fn`.
The C ABI is required for FUSE callbacks that interface with the
native libfuse library.

Hi Wolfgang,
I wanted tp follow up on the patch I submitted about a month ago.
I haven't received any feedback yet and wanted to check if there are any
concerns with the change or if any changes are needed. I'm happy to
revise the patch or provide additional information if that would be
helpful.
Thanks for your time and for maintaining this project!
Regards,
