Subject: [PATCH v6 1/4] proc/meminfo: avoid open coded reading of vm_committed_as
Date: Fri, 10 Jul 2020 22:01:45 +0800 [thread overview]
Message-ID: <1594389708-60781-2-git-send-email-feng.tang@intel.com> (raw)
In-Reply-To: <1594389708-60781-1-git-send-email-feng.tang@intel.com>
Use the existing vm_memory_committed() instead, which is also convenient
for future change.
