[PATCH rdma-next v2 0/7] Expose CQ moderation to user space

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

Changelog:
v1->v2:
 * Replaced word cookie to be CQE in commit messages.
 * Added patch to rename ib_modify_cq() to be rdma_set_moderation()
v0->v1:
 * Dropped comp_mask, there is already attr_mask
 * Put CQ moderartion into special struct instead of general struct
 * ib_uverbs_ex_modify_cq

------------------------------------------------------------------------------
This patch set exposes CQ moderation. This will allow to moderate
number of CQEs needed to create an event. Such change brings performance
improvement by reducing pressure on application to receive event per-CQE.

The proposed semantics follows the well-established kernel semantics.
  * cq_max_count - defines the number of cookies needed to create an event.                                                                                            * cq_period    - defines the timeout between last event and a new one
		   that will occur even if cq_max_count was not reached

The patches are available in the git repository at:
  git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git tags/rdma-next-2017-11-13

	Thanks
