From: Kaixiong Yu <yukaixiong@huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICAVPP -------------------------------- GFP_NOWAIT callers are always prepared for their allocations to fail because they fail so frequently. In such case, don't need to generate a warning. So, add __GFP_NOWARN to flag when allocations.
