[PATCH 0/5] migration/ram: Merge zero page handling

Posted by Fabiano Rosas 9 months ago

Hi,

This is another small series that I extracted from my fixed-ram series
and that could be already considered for merging.

This is just code movement, no functional change. The objective is to
consolidate the zero page handling in the same routine that saves the
page header and does accounting. Then in the future I'll be able to
just return early because fixed-ram ignores zero pages.

CI run: https://gitlab.com/farosas/qemu/-/pipelines/968300062

Fabiano Rosas (5):
  migration/ram: Remove RAMState from xbzrle_cache_zero_page
  migration/ram: Stop passing QEMUFile around in save_zero_page
  migration/ram: Move xbzrle zero page handling into save_zero_page
  migration/ram: Return early from save_zero_page
  migration/ram: Merge save_zero_page functions
