[Qemu-block] [PATCH v4 0/5] qcow2: async handling of fragmented io

2019-08-16 Thread Vladimir Sementsov-Ogievskiy
Hi all! Here is an asynchronous scheme for handling fragmented qcow2 reads and writes. Both qcow2 read and write functions loops through sequential portions of data. The series aim it to parallelize these loops iterations. It improves performance for fragmented qcow2 images, I've tested it as
