[PATCH 0/4] refresh filter parents when child was resized

Posted by Fiona Ebner 4 months, 2 weeks ago

Resizing a node below a filter would result in the filter still
reporting the old size. Implement a 'resize' callback for the
child_of_bds class, that refreshes filter parents recursively.

Fiona Ebner (4):
  include/block/block_int-common: document when resize callback is used
  block: make bdrv_co_parent_cb_resize() a proper IO API function
  block: implement 'resize' callback for child_of_bds class
  iotests: add test for resizing a node below filters
