[merged mm-stable] mm-vmalloc-move-vmap_init_free_space-down-in-vmallocc.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm: vmalloc: move vmap_init_free_space() down in vmalloc.c
has been removed from the -mm tree.  Its filename was
     mm-vmalloc-move-vmap_init_free_space-down-in-vmallocc.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: vmalloc: move vmap_init_free_space() down in vmalloc.c
Date: Tue, 2 Jan 2024 19:46:25 +0100

A vmap_init_free_space() is a function that setups a vmap space and is
considered as part of initialization phase.  Since a main entry which is
vmalloc_init(), has been moved down in vmalloc.c it makes sense to follow
the pattern.

There is no a functional change as a result of this patch.
