When the linux compilation workload runs, the migration time (both the legacy and this optimization case) varies as the compilation goes on. It seems not easy...

...o 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_POISON to page_poison.c and add a function to expose page poison val to kernel modules. v26->v27: - add a new patch to expose page_poisoning_enabled to...
