Subject: [PATCH for-next 4/9] RDMA/hns: Modify pi vlaue when cq overflows
Date: Fri, 9 Aug 2019 17:41:01 +0800 [thread overview]
Message-ID: <1565343666-73193-5-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1565343666-73193-1-git-send-email-oulijun@huawei.com>
From: Yangyang Li <liyangyang20@huawei.com>
When exiting "for loop", the actual value of pi will be
increased by 1, which is compatible with the next calculation.
But when pi is equal to "ci + hr_cq-> ib_cq.cqe", the "break"
was called and the pi is actual value, it will lead one cqe
still existing, so the "==" should be modify to ">".
