The quilt patch titled Subject: maple_tree: use MAS_BUG_ON() in mas_set_height() has been removed from the -mm tree. Its filename was maple_tree-use-mas_bug_on-in-mas_set_height.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 ------------------------------------------------------ From: "Liam R. Howlett" <Liam.Howlett@xxxxxxxxxx> Subject: maple_tree: use MAS_BUG_ON() in mas_set_height() Date: Thu, 18 May 2023 10:55:20 -0400 Use MAS_BUG_ON() instead of MT_BUG_ON() to get the maple state information. In the unlikely event of a tree height of > 31, try to increase the probability of useful information being logged.
