The quilt patch titled Subject: maple_tree: export symbol mas_preallocate() has been removed from the -mm tree. Its filename was maple_tree-export-symbol-mas_preallocate.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: Danilo Krummrich <dakr@xxxxxxxxxx> Subject: maple_tree: export symbol mas_preallocate() Date: Thu, 2 Mar 2023 02:10:35 +0100 Fix missing EXPORT_SYMBOL_GPL() statement for mas_preallocate(). It isn't actually used by anything yet, but mas_preallocate() is part of the maple tree's 'Advanced API'. All other functions of this API are exported already.
