  eal: mark rte_dev API's as stable
  eal: make rte_class API's stable
  eal: make rte_version_XXX API's stable
  eal: make rte_drand a stable API
  eal: make rte_service_lcore_may_be_active stable
  eal: make rte_devargs_reset stable
  eal: make pflock API stable
  eal: make seqcount and seqlock stable
  eal: mark rte_intr_XXX API's as stable
  eal: mark rte_atomic128_cmp_exchange as stable
  eal: make most rte_thread API's stable
  eal: mark rte_power API's stable
  eal: mark rte_eal_vfio_get_token stable
  eal: mark rte_vect simd bandwidth API as stable

I'm wondering if given the fluidity of changes in atomics right now we
should hold this for a little while / close to the end of the merge
window just in case we want to adjust it?

Already acked the series but since i know about this set here's an
explicit ack.

note: i have on my todo list but still haven't managed to get to it
adding the __rte_deprecated to rte_ctrl_thread_create which has a posix
name in the signature. rte_thread_create_control was introduced as a
replacement in .. 23.07.

there is driver work going on for similar functionality to vfio on
windows. it's possible that this api could be exposed for windows but
in the current form may not be suitable.

*not blocking* 

just wanted to make you aware, i don't have a firm enough schedule to
derail this process.

can i ask that this patch be held until this series is merged?

i'm already overloaded with rebasing for other changes, i'm working
