Maybe instead of making the call below bold using `` `` might be better to use

**rte_rcu_qsbr_get_memsize**
``rte_rcu_qsbr_get_memsize``
 
For all of them below

> +Application can call **rte_rcu_qsbr_get_memsize** to calculate the size
> +of memory to allocate. This API takes maximum number of reader threads,
> +using this variable, as a parameter. Currently, a maximum of 1024
> +threads are supported.
> +
> +Further, the application can initialize a QS variable using the API
> +**rte_rcu_qsbr_init**.
> +
> +Each reader thread is assumed to have a unique thread ID. Currently,
> +the management of the thread ID (for ex: allocation/free) is left to
> +the application. The thread ID should be in the range of 0 to maximum
> +number of threads provided while creating the QS variable.
> +The application could also use lcore_id as the thread ID where applicable.
> +
> +**rte_rcu_qsbr_thread_register** API will register a reader thread to
> +report its quiescent state. This can be called from a reader thread.
> +A control plane thread can also call this on behalf of a reader thread.
> +The reader thread must call **rte_rcu_qsbr_thread_online** API to start
> +reporting its quiescent state.
> +
> +Some of the use cases might require the reader threads to make blocking
> +API calls (for ex: while using eventdev APIs). The writer thread should
> +not wait for such reader threads to enter quiescent state.
> +The reader thread must call **rte_rcu_qsbr_thread_offline** API, before
> +calling blocking APIs. It can call **rte_rcu_qsbr_thread_online** API
> +once the blocking API call returns.
> +
> +The writer thread can trigger the reader threads to report their
> +quiescent state by calling the API **rte_rcu_qsbr_start**. It is
> +possible for multiple writer threads to query the quiescent state
> +status simultaneously. Hence,
> +**rte_rcu_qsbr_start** returns a token to each caller.
> +
> +The writer thread has to call **rte_rcu_qsbr_check** API with the token
> +to get the current quiescent state status. Option to block till all the
> +reader threads enter the quiescent state is provided. If this API
> +indicates that all the reader threads have entered the quiescent state,
> +the application can free the deleted entry.
> +
> +The APIs **rte_rcu_qsbr_start** and **rte_rcu_qsbr_check** are lock
> free.
> +Hence, they can be called concurrently from multiple writers even while
> +running as worker threads.
> +
> +The separation of triggering the reporting from querying the status
> +provides the writer threads flexibility to do useful work instead of
> +blocking for the reader threads to enter the quiescent state or go
> +offline. This reduces the memory accesses due to continuous polling for the
> status.
> +
> +**rte_rcu_qsbr_synchronize** API combines the functionality of
> +**rte_rcu_qsbr_start** and blocking **rte_rcu_qsbr_check** into a single
> API.
> +This API triggers the reader threads to report their quiescent state
> +and polls till all the readers enter the quiescent state or go offline.
> +This API does not allow the writer to do useful work while waiting and
> +also introduces additional memory accesses due to continuous polling.
> +
> +The reader thread must call **rte_rcu_qsbr_thread_offline** and
> +**rte_rcu_qsbr_thread_unregister** APIs to remove itself from reporting
> +its quiescent state. The **rte_rcu_qsbr_check** API will not wait for
> +this reader thread to report the quiescent state status anymore.
> +
> +The reader threads should call **rte_rcu_qsbr_update** API to indicate
> +that they entered a quiescent state. This API checks if a writer has
> +triggered a quiescent state query and update the state accordingly.

If it's possible to enlarge the image a bit it would be good to be able to read the lower text
I need to enlarge it to 175% maybe I'm just blind but if it's possible it would be great
