I am unfortunately completely oblivious to bdev handling code. In 2.6.9-rc2-mm1 this corresponds to (whitespace not preserved):
1390 BUG_ON(!hlist_unhashed(&crq->hash)); 1391 1392 if (crq->io_context) 1393 put_io_context(crq->io_context->ioc); 1394 1395 BUG_ON(!cfqq->allocated[crq->is_write]); 1396 cfqq->allocated[crq->is_write]--; 1397 1398 mempool_free(crq, cfqd->crq_pool); 1399 rq->elevator_private = NULL;
