Subject: [PATCH v4 1/4] proc/meminfo: avoid open coded reading of vm_committed_as
Date: Fri, 29 May 2020 09:06:07 +0800 [thread overview]
Message-ID: <1590714370-67182-2-git-send-email-feng.tang@intel.com> (raw)
In-Reply-To: <1590714370-67182-1-git-send-email-feng.tang@intel.com>
Use the existing vm_memory_committed() instead, which is also
convenient for future change.
