Description

Cloned from LU-11595 to capture a related patch being added to that already resolved ticket.

 

The check in ll_dom_finish_open() for data end shouldn't use i_size for comparision because it may be not updated yet with just returned data from server. Use size value in mdt_body from reply for that check.
