[linux-lvm] Patching Linus' pre- kernels?

[Hugo Mills]

   Hi - 

   I've just tried to patch a recent, but otherwise virgin, Linus
kernel, and had the kernel compile fail:

make[2]: Leaving directory `/usr/src/linux-2.4.5-pre3/arch/i386/lib'
ld -m elf_i386 -T /usr/src/linux-2.4.5-pre3/arch/i386/vmlinux.lds -e stext arch/i386/kernel/head.o arch/i386/kernel/init_task.o init/main.o init/version.o \

        --end-group \

make[1]: *** [vmlinux] Error 1
make[1]: Leaving directory `/usr/src/linux-2.4.5-pre3'
make: *** [stamp-build] Error 2

I'm using:
Debian testing
Kernel 2.4.5-pre3
LVM 0.9.1-beta7

   Is the beta7 LVM expected to patch against Linus' pre- kernels? If
it is, what have I done wrong? If not, which kernels should I be able
to patch against?

   Also, are there any potential problems with running LVM and devfs
together?

   Thanks,
   Hugo.
