[dpdk-dev] [PATCH 0/7] Subject: [PATCH ...] Add stack library and new mempool handler

[Gage Eads]

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].
