[PATCH 00/14] migration/ram.c: Refactor compress code |
Date: |
Sun, 2 Apr 2023 17:55:59 +0000 |
This series refactors the ram compress code.
It first removes ram.c dependencies from the core compress code, then
moves it out to its own file. Finally, on the migration destination side
the initialisation and cleanup of compress threads is moved out of ram.c
to migration.c. This allows using COLO with compress enabled.
This series is based on the following series:

Lukas Straub (14):
ram.c: Let the compress threads return a CompressResult enum
ram.c: Dont change param->block in the compress thread
ram.c: Reset result after sending queued data
ram.c: Do not call save_page_header() from compress threads
ram.c: Call update_compress_thread_counts from
compress_send_queued_data
ram.c: Remove last ram.c dependency from the core compress code
ram.c: Introduce whitespace (squash with next patch)
ram.c: Move core compression code into its own file
ram.c: Remove whitespace (squash with previous patch)
ram.c: Move core decompression code into its own file
ram compress: Assert that the file buffer matches the result
ram.c: Remove unused include after moving out code
ram-compress.c: Make target independent
migration: Initialize and cleanup decompression in migration.c
