Subject: [PATCH RFC 1/4] mm/memcontrol: drop unused vmscan tracepoint include
Date: Mon, 21 Sep 2026 19:46:03 +0800	[thread overview]
Message-ID: <20260921114606.3871820-2-ridong.chen@linux.dev> (raw)
In-Reply-To: <20260921114606.3871820-1-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.  Removing the include still compiles
cleanly.
