[Qemu-stable] [v2 0/4] Fix long vm downtime during live migration

[Liang Li]

Some cleanup operations take long time during the pause and copy stage,
especially with the KVM patch 3ea3b7fa9af067, do these operations after
the completion of live migration can help to reduce VM downtime.

Ony the first patch changes the behavior, the rest 3 patches are for code
cleanup.

Changes:
  * Remove qemu_savevm_sate_cancel() in migrate_fd_cleanup()
  * Add 2 more patches for code clean up

Liang Li (4):
  migration: do cleanup operation after completion
  migration: rename qemu_savevm_state_cancel
  migration: rename cancel to cleanup in SaveVMHandles
  migration: code clean up
