Subject: [PATCH RFC v3 1/7] mm/memcontrol: drop unused vmscan tracepoint include
Date: Tue, 13 Oct 2026 21:13:03 +0800 [thread overview]
Message-ID: <20261013131309.2790253-2-ridong.chen@linux.dev> (raw)
In-Reply-To: <20261013131309.2790253-1-ridong.chen@linux.dev>
From: Ridong Chen <chenridong@xiaomi.com>
memcontrol.c includes <trace/events/vmscan.h> but does not use any of
the tracepoints or macros it defines: all tracepoints invoked here come
from memcg.h and writeback.h.
Drop it ahead of moving the vmscan trace header under mm/, after which
<trace/events/vmscan.h> will no longer exist.
No functional change.
