This patchset introduces a stack library, supporting both lock-based and non-blocking stacks, and a non-blocking stack mempool handler.
The lock-based stack code is derived from the existing stack mempool handler, and that handler is refactored to use the stack library. The non-blocking stack mempool handler is intended for usages where the rte ring's "non-preemptive" constraint is not acceptable; for example, if the application uses a mixture of pinned high-priority threads and multiplexed low-priority threads that share a mempool. Note that the non-blocking algorithm relies on a 128-bit compare-and-swap, so it is currently limited to the x86_64 platform. This patchset is the successor to a patchset containing only the new mempool handler[1].
