Subject: [PATCH v4 1/9] mm/memcontrol: drop unused vmscan tracepoint include
Date: Mon, 19 Oct 2026 11:52:44 +0800 [thread overview]
Message-ID: <20261019035252.2357900-1-ridong.chen@linux.dev> (raw)
In-Reply-To: <20261019034426.2354049-1-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.
