From: Andrew Morton <a...@linux-foundation.org>
commit 5143eecd2af2b5424f7b96d53f17bb4718e46bd3 upstream.
Commit 0de56e38b307 ("maple_tree: use maple state end for write
operations") was broken by a later patch "maple_tree: do not preallocate
nodes for slot stores". But the later patch was scheduled ahead of
0de56e38b307, for 6.7-rc.
This fixlet undoes the damage.
Fixes: 0de56e38b307 ("maple_tree: use maple state end for write operations")
