Subject: [PATCH for-rc 1/2] RDMA/hns: Fix to support 64K page for srq
Date: Thu, 24 Oct 2019 17:21:56 +0800 [thread overview]
Message-ID: <1571908917-16220-2-git-send-email-liweihang@hisilicon.com> (raw)
In-Reply-To: <1571908917-16220-1-git-send-email-liweihang@hisilicon.com>
From: Lijun Ou <oulijun@huawei.com>
SRQ's page size configuration of BA and buffer should depend on current
PAGE_SHIFT, or it can't work in scenario of 64K page.
Fixes: c7bcb13442e1 ("RDMA/hns: Add SRQ support for hip08 kernel mode")
