Subject: [PATCH v8 08/14] machine: Tweak the order of topology members in struct CpuTopology
Date: Thu, 2 Sep 2021 19:03:24 +0800 [thread overview]
Message-ID: <20210902110330.18036-9-wangyanan55@huawei.com> (raw)
In-Reply-To: <20210902110330.18036-1-wangyanan55@huawei.com>
Now that all the possible topology parameters are integrated in struct
CpuTopology, tweak the order of topology members to be "cpus/sockets/
dies/cores/threads/maxcpus" for readability and consistency. We also
tweak the comment by adding explanation of dies parameter.
