[merged mm-stable] dax-kmem-resolve-default-online-type-at-probe-time.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: dax/kmem: resolve default online type at probe time
has been removed from the -mm tree.  Its filename was
     dax-kmem-resolve-default-online-type-at-probe-time.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: dax/kmem: resolve default online type at probe time
Date: Sun, 12 Jul 2026 11:45:01 -0400

Resolve the default online type in kmem at probe time explicitly instead
of implicitly inheriting the system default by calling
add_memory_driver_managed().

No behavioral change at this point (still system default).
