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

[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 \
        --start-group \

        --end-group \
        -o vmlinux

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.

Hugo,

there's 2 optional solutions:

- change get_hardblocksize to get_hardsect_size and recompile -or-
- get the recent LVM code from CVS at www.sistina.com

   Someone else (Gergely Tamas; thank you) sent me the same patch,
which compiles with no problems. Thanks.

   I am pleased to report that LVM is now holding /var, /tmp and /usr
on my system, without problems. I shall put /home under LVM as soon as
I can pluck up the courage to trust my backups :) (I have little free
space on this system -- moving things is a bit tight).

   Thank you for your help,
   Hugo.
