[Qemu-devel] [PATCH v5 0/6] add throttle block driver filter |
Date: |

This series adds a throttle block driver filter. Currently throttling is done
at the BlockBackend level. Using block driver interfaces we can move the
throttling to any point in the BDS graph using a throttle node which uses the
existing throttling code. This allows for potentially more complex
configurations (throttling at any point in the graph, chained filters)
v5:
fix crash in 'add aio_context field in ThrottleGroupMember'
fix suggestions in block/throttle.c
v4:
fix suggestions in block/throttle.c
fix suggestions in block/throttle_groups.c
add doc note in BlockDevOptionsThrottle
v3:
fix style error in 'add aio_context field in ThrottleGroupMember'
v2:
change QOM throttle group object name
print valid ranges for uint on error
move frees in throttle_group_obj_finalize()
split throttle_group_{set,get}()
add throttle_recurse_is_first_non_filter()
Manos Pitsidianakis (6):
block: move ThrottleGroup membership to ThrottleGroupMember
block: add aio_context field in ThrottleGroupMember
block: tidy ThrottleGroupMember initializations
block: convert ThrottleGroup to object with QOM
block: add throttle block filter driver
block: add iotest 184 for the throttle filter driver
