//! End-to-end smoke test for the Linux on-demand filesystem: mounts
|
||||||
|
//! `CloudreveFs` on a real FUSE mountpoint backed by a stub Cloudreve server
|
||||||
|
//! and exercises listing, attribute reads, and hydrate-on-open through the
|
||||||
|
//! kernel. Skips gracefully when FUSE is unavailable (CI containers).
