Subject: [PATCH 1/1] RDMA/counter: Allow manually bind QPs with different pids
Git-commit: cbeb7d896c0f296451ffa7b67e7706786b8364c8
Patch-mainline: v5.9-rc1
References: bsc#1152489
 to same counter

In manual mode allow bind user QPs with different pids to same counter,
since this is allowed in auto mode.
Bind kernel QPs and user QPs to the same counter are not allowed.

Fixes: 1bd8e0a9d0fd ("RDMA/counter: Allow manual mode configuration support")
