From 5eb56d2520fe16f00756ccdf8eebc277398e0f44 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Tue, 27 Mar 2012 17:09:18 +0300 Subject: Btrfs: fix memory leak in resolver code init_ipath() allocates btrfs_data_container which is never freed. Free it in free_ipath() and nuke the comment for init_data_container() - we can safely free it with kfree().
