From f25708dbf2b33e252b2e912850bb991ff47a2fce Mon Sep 17 00:00:00 2001 From: Jiewei Ke Date: Fri, 27 Dec 2019 19:36:13 +0800 Subject: [PATCH] RDMA/rxe: Fix error type of mmap_offset [ 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.
