The patch titled
Subject: radix tree test suite: add tests for radix_tree_locate_item()
has been removed from the -mm tree. Its filename was
radix-tree-test-suite-add-tests-for-radix_tree_locate_item.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Matthew Wilcox <willy@xxxxxxxxxxxxxxx>
Subject: radix tree test suite: add tests for radix_tree_locate_item()
Fairly simple tests; add various items to the tree, then make sure we can
find them again. Also check that a pointer that we know isn't in the tree
is not found.
