/* This list of free query batches has dual usage depending if
* the command pool is a vn_feedback_pool. The usage is exclusive
* and the list only contains recycled query batches allocated
* from the cmd pool itself so no locking is needed between the two
* usages.

* For feedback cmd pool, batch alloc and free with the free list is
* during queue submissions. Thus proper locking is needed since
* submissions with different queues are not externally synchronized.
*
* For a normal cmd pool, it recycles query batches used for
* injecting query copies/resets and merging batches for secondary
* command buffers during recording. No additional locking is needed
* as those commands are already protected by external synchronization.
