Precedence: bulk


The quilt patch titled
     Subject: mm: vmscan: drop unused gfp_mask parameter from __node_reclaim()
has been removed from the -mm tree.  Its filename was
     mm-vmscan-drop-unused-gfp_mask-parameter-from-__node_reclaim.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm: vmscan: drop unused gfp_mask parameter from __node_reclaim()
Date: Fri, 24 Jul 2026 11:34:34 +0800

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.
