[merged mm-stable] maple_tree-make-test-code-work-without-debug-enabled.patch removed from -mm tree

[Andrew Morton]

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.
