    Subject[2.4 patch] disallow modular BINFMT_ELF
    Hi Marcelo,

    with no 2.4 kernel BINFMT_ELF=m actually worked, you always get a

    <-- snip -->

    depmod: *** Unresolved symbols in /lib/modules/2.4.25-pre4/kernel/fs/binfmt_elf.o
    depmod: smp_num_siblings
    depmod: put_files_struct
    depmod: steal_locks

    <-- snip -->


    Since BINFMT_ELF=m is a very unusual case, the patch below simply
    disallows modular BINFMT_ELF.

    A similar patch I sent was already accepted into 2.6.
