# Rationale for this change
<!--

the issue then this section is not needed.

-->
Expose the internal semaphore used by `ConcurrentLimitLayer` so external
components can coordinate concurrency
with OpenDAL without reinventing their own limiters.
# What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
- Added operation_semaphore() to return the layer’s shared Arc<Semaphore>.
- Expanded the method’s docs to warn about modifying permits.
- Added a unit test demonstrating that holding the shared semaphore blocks
layer operations until released.
# Are there any user-facing changes?
Yes. Applications can now reuse ConcurrentLimitLayer’s semaphore directly
to align their own concurrency
controls with OpenDAL.
<!--
If there are user-facing changes then we may require documentation to be
