CONFIG_MEM_POOL_SPLIT_ONLY:

This option instructs a memory pool to try splitting a larger unused block if an unused block of the required size is not available; if no such blocks exist the block allocation operation fails. This policy attempts to limit the cost of defragmenting the memory pool by avoiding automatic partial defragmentation, at the cost of requiring the application to explicitly request a full defragmentation of the memory pool when an allocation fails. Depending on how a memory pool is used, it may be more efficient for a memory pool to perform an occasional full defragmentation than to perform frequent partial defragmentations.
