Unknown symbol __umoddi3 / ... __udivdi3

[Pierre Etchemaite]

    Hello all,

First, I believe log based filesystems are the future; Not only for 
snapshot feature, but also because they can give superior performance 
(vs. standard filesystems) on modern disks, cf

http://citeseer.ist.psu.edu/694627.html

for a very interesting performance analysis.


Now, back to more down-to-earth considerations :)
I'd like to give the nilfs 2.0.0-testing7 release a try with linux 
kernel 2.6.23, but I can't load the kernel module; dmesg says

nilfs2: Unknown symbol __umoddi3
nilfs2: Unknown symbol __udivdi3
nilfs2: Unknown symbol __umoddi3
nilfs2: Unknown symbol __udivdi3
nilfs2: Unknown symbol __umoddi3
nilfs2: Unknown symbol __udivdi3

CPU is an AMD64 but used in 32 bit mode, and it seems that 64 bit 
divisions are a problem for 32 bit kernels :/
Any idea how to get around that? (using asm/div64.h?)

Best regards,
Pierre.

We apologize for making no reply to your report. 
The problem will be fixed soon, I hope.  We make some work around
or patches and send them to this ML. Could you try again later?

Thank you.

Sure, no problem. This project is really interesting.

Best regards,
