From 379cde741b220091d2124fb500b178b90ad7f460 Mon Sep 17 00:00:00 2001 From: Stefan Behrens Date: Wed, 8 May 2013 08:56:09 +0000 Subject: Btrfs: fix possible memory leak in replace_path() In replace_path(), if read_tree_block() fails, we cannot return directly, we should free some allocated memory otherwise memory leak happens. Similar to Wang's "Btrfs: fix possible memory leak in the find_parent_nodes()" patch, the current commit fixes an issue that is related to the "Btrfs: fix all callers of read_tree_block" commit.
