[Qemu-devel] [PATCH 0/3] add bdrv_co_drain_begin/end BlockDriver callbacks

[Manos Pitsidianakis <el13635@mail.ntua.gr>]

This patch series renames bdrv_co_drain to bdrv_co_drain_begin and adds a new 
bdrv_co_drain_end callback to match bdrv_drained_begin/end and 
drained_begin/end of BdrvChild. This is needed because the throttle driver 
(block/throttle.c) needs a way to mark the end of the drain in order to toggle 
io_limits_disabled correctly.

Based-on: <20170918202529.28379-1-el13635@mail.ntua.gr>

  block: rename bdrv_co_drain to bdrv_co_drain_begin
  block/throttle.c: add bdrv_co_drain_begin/end callbacks
