Well, with just-released 2.6.27.32 exactly the same issue occurs.
I used patch-2.6.27.32.bz2 on top of linux-2.6.26.tar.bz2, not
the tarball (linux-2.6.27.32.tar.bz2).

fs/ocfs2/aops.c: In function 'ocfs2_write_cluster':
fs/ocfs2/aops.c:1286: error: 'should_zero' undeclared (first use in this function)
fs/ocfs2/aops.c:1286: error: (Each undeclared identifier is reported only once
fs/ocfs2/aops.c:1286: error: for each function it appears in.)
fs/ocfs2/aops.c: In function 'ocfs2_write_cluster_by_desc':
fs/ocfs2/aops.c:1360: warning: passing argument 4 of 'ocfs2_write_cluster' makes pointer from integer without a cast
fs/ocfs2/aops.c:1360: warning: passing argument 6 of 'ocfs2_write_cluster' from incompatible pointer type
fs/ocfs2/aops.c:1360: warning: passing argument 7 of 'ocfs2_write_cluster' makes integer from pointer without a cast
fs/ocfs2/aops.c:1360: error: too many arguments to function 'ocfs2_write_cluster'

Which add-on you're referring to?  In the stable-queue/releases/2.6.27.32/
I only see two patches related to ocfs:
 ocfs2-initialize-the-cluster-we-re-writing-to-in-a-non-sparse-extend.patch
 ocfs2-ocfs2_write_begin_nolock-should-handle-len-0.patch
Neither of which looks like an addon, and only one (the first)
has references to this "should_zero" variable.

Thanks!
