[Qemu-devel] [PATCH 0/3] add bdrv_co_drain_begin/end BlockDriver callbacks
Posted by Manos Pitsidianakis 6 years, 6 months ago
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/throttle-groups.c: allocate RestartData on the heap"
    Which fixes a coroutine crash in block/throttle-groups.c

Manos Pitsidianakis (3):
  block: add bdrv_co_drain_end callback
  block: rename bdrv_co_drain to bdrv_co_drain_begin
  block/throttle.c: add bdrv_co_drain_begin/end callbacks
