JFFS2 uses kmem_cache_alloc() to allocate an ubifs_inode. The memory returned from kmem_cache_alloc() is not zeroed. jffs2_alloc_inode() zeroes all fields in the ubifs_inode except the embedded struct inode. In Linux this is done in the kmem_cache constructor function which calls inode_init_once(). In barebox we have the constructor function as well, but we don't have an equivalent of inode_init_once(), so the constructor is empty. zero the inode in the constructor instead so that barebox gets a zeroed inode.
