[PATCH v2 0/6] migration removals & deprecations

Posted by Fabiano Rosas 1 week, 4 days ago

[respinning because master moved and there were conflicts]

Hi everyone,

Here's some cleaning up of deprecated code. It removes the old block
migration and compression code. Both have suitable replacements in the
form of the blockdev-mirror driver and multifd compression,
respectively.

There's also a deprecation for fd: + file to cope with the fact that
the new MigrationAddress API defines transports instead of protocols
(loose terms) like the old string API did. So we cannot map 1:1 from
fd: to any transport because fd: allows *both* file migration and
socket migration.

v1:
https://lore.kernel.org/r/20240425150939.19268-1-farosas@suse.de

Fabiano Rosas (6):
  migration: Remove 'skipped' field from MigrationStats
  migration: Remove 'inc' option from migrate command
  migration: Remove 'blk/-b' option from migrate commands
  migration: Remove block migration
  migration: Remove non-multifd compression
  migration: Deprecate fd: for file migration
