[PATCH for-next v12 0/6] Move two object pools to rxe_mcast.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series completes the separation of the mc_grp and mc_elem
object pools from rxe_pools.c and moving of their code to rxe_mcast.c.
This makes sense because these two pools are different from the other
pools as the only ones that do not share objects with rdma-core and
that use key's instead of indices to enable looking up objects. This
change will enable a significant simplification of the normal object
pools.

These patches correspond to 08-11/11 of the previous version of this
series. The earler patches have been accepted.
