This time I tested this patch set on both ARM64 and x86 server, against
5.4-rc8.
On ARM64, similar test case and the similar performance improvement.
On X86, I tested on a 24 cores Xeon(R) CPU E5-2620, with kernel compile
(make -j) for test case, and no issue was found.
Tested-by: Hanjun Guo <guohanjun@huawei.com>
