Vladimir Sementsov-Ogievskiy 999658a05e block/io: fix copy_range ... Here two things are fixed: 1. Architecture On each recursion step, we go to the child of src or dst, only for one of them. So, it's wrong to create tracked requests for both on each step. It leads to tracked requests duplication. 2. Wait for serializing requests on write path independently of BDRV_REQ_NO_SERIALISING Before commit 9ded4a0114 "backup: Use copy offloading", BDRV_REQ_NO_SERIALISING was used for only one case: read in copy-on-write operation during backup. Also, the flag was handled only on read path (in bdrv_co_preadv and bdrv_aligned_preadv). After 9ded4a0114, flag is used for not waiting serializing operations on backup target (in same case of copy-on-write operation). This behavior change is unsubstantiated and potentially dangerous, let's drop it and add additional asserts and documentation.
