The patch titled
     Subject: radix-tree: rename radix_tree_is_indirect_ptr()
has been removed from the -mm tree.  Its filename was
     radix-tree-rename-radix_tree_is_indirect_ptr.patch

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

------------------------------------------------------
From: Matthew Wilcox <willy@xxxxxxxxxxxxxxx>
Subject: radix-tree: rename radix_tree_is_indirect_ptr()

As with indirect_to_ptr(), ptr_to_indirect() and RADIX_TREE_INDIRECT_PTR,
change radix_tree_is_indirect_ptr() to radix_tree_is_internal_node().
