From 18d154f57583dd06f0ce3e69e4952044490b2bc4 Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Tue, 30 Apr 2024 11:27:34 -0300 Subject: migration: Remove 'blk/-b' option from migrate commands The block migration is considered obsolete and has been deprecated in 8.2. Remove the migrate command option that enables it. This only affects the QMP and HMP commands, the feature can still be accessed by setting the migration 'block' capability. The whole feature will be removed in a future patch. Deprecation commit 8846b5bfca ("migration: migrate 'blk' command option is deprecated.").
