I've applied the patch to 2.6.32.7 - strangely the patch program segfaulted but
applied the patch correctly.
[root@echo2 linux-2.6.32.7]# patch -p1 < patch
patching file fs/ext4/inode.c
Segmentation fault
Feb 10 02:11:57 echo2 kernel: patch[18919]: segfault at 0 ip 0000003a0c07ee70
sp 00007fff85523278 error 4 in libc-2.10.1.so[3a0c000000+164000]
Also, before booting the new kernel I did a df, /data6 had a negative used
block count. I guess this could be related to the current problem if the ref
counting has gone a bit skew-whiff although this is with the system running
2.6.32.2.

I unmounted and ran fsck, it said it was clean and when I remounted it appeared
to fix itself.

The patched kernel is running on 3 servers - watch this space..
