Experimental tags can be removed from APIs in module: ticket lock, 
MCS lock, pause (wait until equal APIs), and RCU (except for defer
queue APIs) as they have been aroud four releases.

Joyce Kong (4):
  eal/ticketlock: remove experimental tag
  eal/mcslock: remove experimental tag
  rcu: remove experimental tag from QSBR mechanism
  eal/pause: remove experimental tag from wait until equal

As rte_ticketlock was introduced in 19.05 release
and there were no changes in its public API since
19.11 release, it should be mature enough to remove
the experimental tag.

Since rte_mcslock APIs were introduced in 19.08 release,
it is now possible to remove the experimental tag from:
rte_mcslock_lock()
rte_mcslock_unlock()
rte_mcslock_trylock()
rte_mcslock_is_locked()

RCU library supporting quiescent state was introduced
in 19.05 release and has been around 4 releases, it
should be mature enough to remove the experimental tag.

rte_wait_until_equal_xx APIs were introduced in 19.11 release
and there were no changes in the public APIs since then, it
should be mature enough to remove the experimental tag.

Are you fine with those API being marked as stable (especially the
wait until equal API)?

I will handle the Ray comment on the rcu map.

One additional comment: the wait until equal API should be marked

former.
This is just a question of ordering the patches, easy to do when applying.

No need for a v2 on those comments.
