Subject: RDS: IB: handle the RDMA CM time wait event
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=37ea401e9ccc44453da6785514bb64ad6e9c181f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

RDS: IB: handle the RDMA CM time wait event

Drop the RDS connection on RDMA_CM_EVENT_TIMEWAIT_EXIT so that
it can reconnect and resume.

While testing fastreg, this error happened in couple of tests but
was getting un-noticed.
