Subject: [PATCH 3/3] mm: vmscan: drop unused gfp_mask parameter from __node_reclaim()
Date: Fri, 17 Jul 2026 19:33:00 +0800 [thread overview]
Message-ID: <20260717113300.214717-4-ridong.chen@linux.dev> (raw)
In-Reply-To: <20260717113300.214717-1-ridong.chen@linux.dev>
From: Ridong Chen <chenridong@xiaomi.com>
Commit 57972c78e678 ("mm/vmscan: make __node_reclaim() more generic")
moved the scan_control construction out to the callers and passed the
struct in by pointer. After that change every use of the gfp mask inside
__node_reclaim() goes through sc->gfp_mask, leaving the gfp_mask parameter
unused. Just remove the dead parameter and update the callers accordingly.
No functional change.
