large allocation groups fix

Hi.

I'm running a vendor modified kernel 2.4.20-pre2 into
which I have patched the 1.3.1 xfs 2.4.21 patches. 
Doing this wasn't too tricky although I needed to
integrate a few bitkeeper changesets to get this to
work.

I'm using xfs on large filesystems 1TB+ and have
quickly noticed the problem with the large allocation
group size that the latest version of mkfs.xfs will
create by default.  I would like to 'fix' my kernel so
that allocation group sizes above 4GB don't result in
lockups.

Is there a patch I can use against the 1.3.1 xfs
release?   I've looked at the fix included in kernel
changeset 1.1276.1.2 
http://linux.bkbits.net:8080/linux-2.4/cset@xxxxxxxxxx?nav=index.html|src/|src/fs|src/fs/xfs|related/fs/xfs/xfs_iomap.h
but it doesn't apply to the official xfs release.

On a related point, are there any plans to announce
any more official xfs releases or is it just assumed
that people will use upto date linux kernels?

Thanks,
Alex
