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.
