Problem when Patching the kernel for largeblocksize

Problem when Patching the kernel for largeblocksize

[hongqian]

I get the patch from /pub/linux/kernel/people/christoph/largeblocksize/4

the kernel is linux-2.6.22-rc4

I build the kernel with such warnings:

Can anyone help ?

And any patch for kernel 2.6.24 .

Best regards !

Why ask -fsdevel, rather than, say, Christoph?

The largeblock patch has not been updated in awhile now. I am working on 
getting some of the lower level things into shape. Currently working on 
page flags, then we need virtual compoun page support and the pagecache 
function cleanups before we can get to the main patchset.

Maybe I can get an updated git tree done (if I get some time). Would 
people be interested in helping to develop and debug this thing?
