Subject: [PATCH AUTOSEL 5.4 240/459] RDMA/rxe: Fix error type of mmap_offset
Date: Fri, 14 Feb 2020 10:58:10 -0500 [thread overview]
Message-ID: <20200214160149.11681-240-sashal@kernel.org> (raw)
In-Reply-To: <20200214160149.11681-1-sashal@kernel.org>
From: Jiewei Ke <kejiewei.cn@gmail.com>
[ Upstream commit 6ca18d8927d468c763571f78c9a7387a69ffa020 ]
The type of mmap_offset should be u64 instead of int to match the type of
mminfo.offset. If otherwise, after we create several thousands of CQs, it
will run into overflow issues.
