Besides the restructuring agreed in my reply to Alexei, dropping iocg_init()/iocg_free() and moving everything into blk-iocost.c, the series still has problems, which I replied to on the patches. The cover letter is still long and narrates mechanics, and it still carries the v9 and v10 changelogs. Thanks. -- tejun
