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.

CI run: https://gitlab.com/farosas/qemu/-/pipelines/1267859704

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

Doesn't apply for me.  What's your base?

88daa112d4 ("Merge tag 'migration-20240423-pull-request' of
https://gitlab.com/peterx/qemu into staging")

Probably clashed with the other removals from Philippe.
