This series enables grouping verbs objects together for the purpose of optimizing the behavior of the driver in a multi-threaded environment. The first use of this will be for mlx5 to group UAR registers in a way that avoids needing locking on the post send path. The series follows an RFC and a detailed discussion over it in the ML, the matching kernel side was sent to rdma-next for 4.16. A detailed description of the API and its usage appears as part of the man pages and the commit logs which are part of the series.
