Btrfs: use kmem_cache_free when freeing entry in inode cache
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().
