This happens with our own kernel, so the line number can't match with 
upstream kernel.

static void break_stripe_batch_list(struct stripe_head *head_sh,
                                     unsigned long handle_flags)
{
         struct stripe_head *sh, *next;
         int i;
         int do_wakeup = 0;

         list_for_each_entry_safe(sh, next, &head_sh->batch_list, 
batch_list) {

                 list_del_init(&sh->batch_list);

*WARN_ONCE(sh->state & ((1 << STRIPE_ACTIVE) |*

The warning was happened at above line.

Thanks,
