From 4dd6c0987ca43d6544f4f0a3f86f6ea3bfc60fc1 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 20 May 2016 17:03:27 -0700 Subject: radix-tree: rename indirect_to_ptr() to entry_to_node() Mirrors the earlier commit introducing node_to_entry(). Also change the type returned to be a struct radix_tree_node pointer. That lets us simplify a couple of places in the radix tree shrink & extend paths where we could convert an entry into a pointer, modify the node, then convert the pointer back into an entry.
