This is most definitively a build issue. But "what" is unknown.
How comfortable are you playing with the source? If so,
I could guide you in debugging the issue. If not, I can make
a patch that you could build and run.
In short, the error is originating from here.
fs/ocfs2/cluster/tcp.c
if (sc->sc_page_off == sizeof(struct o2net_msg)) {
hdr = page_address(sc->sc_page);
if (be16_to_cpu(hdr->data_len) >
O2NET_MAX_PAYLOAD_BYTES)
ret = -EOVERFLOW;
}
