Its filename was mm-collapse-name-the-per-table-scan-reset-for-what-it-resets.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: "Kiryl Shutsemau (Meta)" Subject: mm/collapse: name the per-table scan reset for what it resets Date: Mon, 28 Sep 2026 11:06:21 +0100 collapse_control_init_scan() resets what one scan accumulates: the node load, the allocation nodemask and the eligible-PTE bitmap. It runs before every PTE table a scan is given, not once per control, so its name points at the wrong thing. Call it collapse_scan_reset(). Preparation for giving a control a real init and release, run once each for a whole series of scans. Two names a word apart would then stand for two different jobs. No functional change.
