Compiling module for 2.6.23 kernel, unrecognized symbols.

[StifflerStealth]

Hi,

I just updated the my kernel to 2.6.23 from 2.6.22. I used the previous config file, and I recompiled the module from an ebuild, but I still get un recognized symbol errors.

What do I need to enable in the kernel for there sysmbols:
lookup_one_len_nd
page_cache_readahead
kmem_cache_zalloc
filemap_populate
cancel_rearming_delayed_work
filemap_nopage
filemap_populate

I was able to cut that list in half. This is a filesystem module that is not part of the kernel, and the devs say it is compatible with 2.6.23. I just need the correct symbols exported. I tried looking online using google, but I get links with patches and .c files, which doesn't tell me what config option it is.

Thanks.
