Subject: [PATCH 4/6] mm/vmstat: Inline NUMA event counter updates
Date: Mon, 29 Mar 2021 13:06:46 +0100 [thread overview]
Message-ID: <20210329120648.19040-5-mgorman@techsingularity.net> (raw)
In-Reply-To: <20210329120648.19040-1-mgorman@techsingularity.net>
__count_numa_event is small enough to be treated similarly to
__count_vm_event so inline it.
