Subject: RPC/RDMA: ensure connection attempt is complete before signalling.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c055551e97e1ca00781bc41523f829e05a8afed7;p=linux-beck.git

RPC/RDMA: ensure connection attempt is complete before signalling.

The RPC/RDMA connection logic could return early from reconnection
attempts, leading to additional spurious retries.
