The spdk_mem_reserve() function reserves a memory region in SPDK's memory maps. This pre-allocates all of the required data structures to hold memory address translations for that region without actually populating the region. After a region is reserved, calls to spdk_mem_register() for addresses in that range will not require any internal memory allocations. This is useful when overlaying a custom memory allocator on top of SPDK's hugepage memory, such as tcmalloc.
