btrfs without acl

Hello everyone,

trying to build btrfs-0.16 without acl support (CONFIG_FS_POSIX_ACL unset) results in the following error messages for me:

fs/built-in.o: In function `btrfs_permission':
inode.c:(.text+0x61250): undefined reference to btrfs_check_acl' fs/built-in.o: In function btrfs_create':
inode.c:(.text+0x63bdf): undefined reference to btrfs_init_acl' fs/built-in.o: In function btrfs_mknod':
inode.c:(.text+0x63eef): undefined reference to btrfs_init_acl' fs/built-in.o: In function btrfs_mkdir':
inode.c:(.text+0x6410b): undefined reference to btrfs_init_acl' fs/built-in.o: In function btrfs_symlink':

inode.c:(.text+0x66443): undefined reference to `btrfs_acl_chmod'

Looking at the unstable tree I do not think this is fixed yet.
