3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Filipe Manana <fdmanana@xxxxxxxx> commit c3f4a1685bb87e59c886ee68f7967eae07d4dffa upstream. The free space entries are allocated using kmem_cache_zalloc(), through __btrfs_add_free_space(), therefore we should use kmem_cache_free() and not kfree() to avoid any confusion and any potential problem. Looking at the kfree() definition at mm/slab.c it has the following comment: /* * (...) * * Don't free memory not originally allocated by kmalloc() * or you will run into trouble. */ So better be safe and use kmem_cache_free().
