Actually, -EOVERFLOW appears throughout the kernel.  A couple examples:

drivers/net/ppp_generic.:ppp_read() uses it to indicate skb->len >
sizeof buffer to put the data into.

fs/stat.c:cp_new_stat() and friends
    if (stat->size > MAX_NON_LFS)
          return -EOVERFLOW;
indicates that the file size is larger than can be represented by the app.

I believe our use would be consistent.

Thanks,
Matt
