[Qemu-devel] [RFC PATCH 0/3] block: qiov_offset parameter for io

[Vladimir Sementsov-Ogievskiy]

Hi all!

Here is idea of adding qiov_offset parameter to io path, to avoid
a lot of places with same pattern of creating local_qiov or hd_qiov
variables. Here is only read path for qcow2, if we like it, I'll
make v2 with both read and write paths for qcow2.

Vladimir Sementsov-Ogievskiy (3):
  block/io: introduce bdrv_co_preadv_part
  block/qcow2: refactor qcow2_co_preadv to use buffer-based io
  block/qcow2: implement .bdrv_co_preadv_part
