...the legacy live migration takes ~1817ms. With this optimization, it takes ~254ms, which reduces the time to 14%. - Workload tests Results: Running this feature has no impact on the linux compilation workload running inside the guest. Details: Set up a Ping-Pong local live migration, where the guest ceaselessy migrates between the source and destination. Linux compilation, i.e. make bzImage -j4, is performed during the Ping-Pong migration. The legacy case takes 5min14s to finish the compilation. With this optimization patched, it takes 5min12s. ChangeLog: v27->v28: - mm/page_poison: Move PAGE_POI...
