From: Miklos Szeredi <mszeredi@xxxxxxxxxx> [ Upstream commit 0a7419c68a45d2d066b996be5087aa2d07ce80eb ] get_user_ns() is done twice (once in virtio_fs_get_tree() and once in fuse_conn_init()), resulting in a reference leak. Also looks better to use fsc->user_ns (which *should* be the current_user_ns() at this point).
