[Dazuko-devel] dazuko for linux 3.x?

[Erik Miller]

This project has been stagnant for a while. I wanted to see how hard
it would be to get it running with a 3.0 or 3.2 linux kernel.  I'm not
a strong programmer, but I started converting it over today. With any
luck maybe we can get it working again.

it compiles okay, but it doesn't appear to do anything. I think the
problem might be in the dazukofs_d_compare function in the dentry.c
file, ~= line 159, which was not converted over correctly.

Anyone have any ideas?
