[Andrew Morton]

The quilt patch titled
     Subject: mm: memcontrol: update state_local when flushing NMI stats
has been removed from the -mm tree.  Its filename was
     mm-memcontrol-update-state_local-when-flushing-nmi-stats.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: memcontrol: update state_local when flushing NMI stats
Date: Mon, 13 Jul 2026 16:50:53 +0800

flush_nmi_stats() updates state[] for kmem and slab counters but leaves
the corresponding state_local[] counters unchanged.  Local kmem and slab
statistics therefore miss updates collected through the NMI-safe atomic
path.

Update state_local[] together with state[].
