The quilt patch titled
Subject: maple_tree: make test code work without debug enabled
has been removed from the -mm tree. Its filename was
maple_tree-make-test-code-work-without-debug-enabled.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: maple_tree: make test code work without debug enabled
Date: Thu, 18 May 2023 10:55:25 -0400
The test code is less useful without debug, but can still do general
validations. Define mt_dump(), mas_dump() and mas_wr_dump() as a noop if
debug is not enabled and document it in the test module information that
more information can be obtained with another kernel config option.
MT_BUG_ON() will report a failures without tree dumps, and the output will
be less useful.
