Subject: [PATCH 10/19] radix-tree: Rename indirect_to_ptr() to entry_to_node()
Date: Thu, 14 Apr 2016 10:37:13 -0400 [thread overview]
Message-ID: <1460644642-30642-11-git-send-email-willy@linux.intel.com> (raw)
In-Reply-To: <1460644642-30642-1-git-send-email-willy@linux.intel.com>
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.
