[PATCH v3 0/4] migration: Fix disorder of channel creations |

v3
- Fix indent for uri_supports_multi_channels() [Juan]
- Rename migration_uri_validate() to migration_channels_and_uri_compatible()
[Juan]
- Separate the changes to migrate_postcopy_preempt() into separate patch [Juan]
I can trigger disordered connections with preempt mode postcopy (1 out of a
few attemps), which can cause migration to hang during precopy phase, if
e.g. I set the NIC packet loss rate to 50%.
The last patch fixes the real ordering issue. For each of the patch,
please refer to the commit message and comments in-code.
Any comment welcomed, thanks.
Peter Xu (4):
migration: Rework multi-channel checks on URI
migration: Cleanup postcopy_preempt_setup()
migration: Add a semaphore to count PONGs
migration: Postpone postcopy preempt channel to be after main
