Both kernel/exit.c and fs/dcache.c refer to functions in kernel/futex.c which is not built unless CONFIG_FUTEX is true. This causes a build failure at link time:
LD vmlinux
kernel/built-in.o(.text+0xab58): In function `do_exit':
/usr/src/linux-2.6.14-rc/kernel/exit.c:851: undefined reference to `exit_futex'
fs/built-in.o(.text+0x1b2bf): In function `dput':
/usr/src/linux-2.6.14-rc/fs/dcache.c:165: undefined reference to `futex_free_robust_list'
This problem is specific to the robust-futexes patch.
