+New AIO rate-limiting VFS module
+--------------------------------
+A new VFS stackable module has been introduced to implement rate-limiting for
+asynchronous I/O operations. Administrators can now enforce throughput ceilings
+by defining limits in either operations per second or bytes per second. The
+module utilizes a token-based algorithm to calculate real-time I/O load; when
+limits are exceeded, it dynamically injects millisecond delays into async
+operations to maintain the defined threshold.
