The patch titled
     Subject: lib/radix-tree.c: update the kmemleak stack trace for radix tree allocations
has been removed from the -mm tree.  Its filename was
     lib-update-the-kmemleak-stack-trace-for-radix-tree-allocations.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Catalin Marinas <catalin.marinas@arm.com>
Subject: lib/radix-tree.c: update the kmemleak stack trace for radix tree allocations

Since radix_tree_preload() stack trace is not always useful for debugging
an actual radix tree memory leak, this patch updates the kmemleak
allocation stack trace in the radix_tree_node_alloc() function.
