[PATCH v2 0/6] Eliminate multifd flush |

Hi
In this v2:
- update to latest upstream
- change 0, 1, 2 values to defines
- Add documentation for SAVE_VM_FLAGS
- Add missing qemu_fflush(), it made random hangs for migration test
(only for tls, no clue why).
Please, review.
[v1]
Upstream multifd code synchronize all threads after each RAM section. This is
suboptimal.
Change it to only flush after we go trough all ram.
Preserve all semantics for old machine types.
Juan Quintela (6):
multifd: Create property multifd-sync-after-each-section
multifd: Protect multifd_send_sync_main() calls
migration: Simplify ram_find_and_save_block()
migration: Make find_dirty_block() return a single parameter
multifd: Only sync once each full round of memory
ram: Document migration ram flags
