+## Tasklet
+
+A tasklet is a bottom-half mechanism based on softirq, used to execute lightweight, non-sleepable callback logic within a softirq context.
+
+### Semantic Highlights
+
+- Can be scheduled in hardirq/softirq/task context.  
+- Only one instance of the same tasklet can execute at a time (self-serializing).  
+- Repeated scheduling is deduplicated and will not enqueue indefinitely.  
+- Callbacks run in a softirq context, where sleeping is not allowed.  
+
+### Data Passing
+
+The tasklet callback is abstracted through the `TaskletFunc` trait, with an equivalent function signature:
+
+```rust
+fn(usize, Option<Arc<dyn TaskletData>>)
+```
+
+- `usize` is suitable for simple values or indices.  
+- `Option<Arc<dyn TaskletData>>` is suitable for complex data that requires safe sharing.  
+
+`TaskletData` is constrained to `Send + Sync`, and is safely shared via `Arc` to avoid passing raw pointers.
