From bdc924bb4cdac92b945945c3149ab8191c92d75d Mon Sep 17 00:00:00 2001 From: Ian Kent Date: Mon, 27 Dec 2010 16:33:15 +0800 Subject: [PATCH] Btrfs: Fix memory leak on finding existing super We missed a memory deallocation in commit 450ba0ea. If an existing super block is found at mount and there is no error condition then the pre-allocated tree_root and fs_info are no not used and are not freeded.
