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@xxxxxxx>
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.
