The quilt patch titled
     Subject: mm/collapse: name the per-table scan reset for what it resets
has been removed from the -mm tree.  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

Subject: mm/collapse: name the per-table scan reset for what it resets
Date: Wed, 16 Sep 2026 10:31:34 +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.
