Re: drbd 8.0.2/3 doesn't load under kernel 2.6.21

John,

What's story with this? I just tried the patch for 2.6.22 and your patch is still trashing the kernel, preventing drbd from being compiled in.

Anyone else have any idea how these apparently simple network patches could render these symbols inaccessible to the kernel?


It turns out I was adding the web100 patch (http://www.web100.org) to
the 2.6.21 kernel and that's what causes the symbol resolving problem
below. Adding the corresponding version of the web100 patch to the
2.6.20 kernel makes this problem appear there as well. On fresh
versions of the kernel, this problem does not occur. At the moment,
it's not possible to have a current kernel that contains both drbd
and web100.

On a 64-bit Gentoo system with Gentoo's 2.6.21 kernel, drbd 8.0.2/3
complains when I try to load the module:

[  134.141363] drbd: Unknown symbol cn_fini
[  134.141399] drbd: Unknown symbol cn_init

It works fine when I compile it and load in the previous kernel
version, 2.6.20 and the symbols are present in the map file

./System.map-genkernel-x86_64-2.6.21-gentoo-r2:ffffffff802935aa t cn_fini
./System.map-genkernel-x86_64-2.6.21-gentoo-r2:ffffffff8029362a t cn_init

I am c'cing the kernel mailing list because this appears to be a
problem with how any module accesses symbols in the kernel, not just
 >drbd. Source was compiled with Gentoo gcc-4.1.2, glibc-2.5-r3
