<p>Specify this flag to enable linear allocation algorithm, which always creates new allocations after last one and doesn't reuse space from allocations freed in between. It trades memory consumption for simplified algorithm and data structure, which has better performance and uses less memory for metadata.</p>
<p>By using this flag, you can achieve behavior of free-at-once, stack, ring buffer, and double stack. For details, see documentation chapter <aclass="el"href="custom_memory_pools.html#linear_algorithm">Linear allocation algorithm</a>. </p>

<p>This algorithm is based on 2-level lists dividing address space into smaller chunks. The first level is aligned to power of two which serves as buckets for requested memory to fall into, and the second level is lineary subdivided into lists of free memory. This algorithm aims to achieve bounded response time even in the worst case scenario. Allocation time can be sometimes slightly longer than compared to other algorithms but in return the application can avoid stalls in case of fragmentation, giving predictable results, suitable for real-time use cases. </p>
