v1: https://lore.kernel.org/r/20241205185303.897010-1-pet...@redhat.com v2: https://lore.kernel.org/r/20241206005834.1050905-1-pet...@redhat.com v3 changelog: - R-bs collected - Update commit message of patch 1 [Fabiano] - English updates [Fabiano] - Update comment for MULTIFD_SYNC_ALL [Fabiano] - In multifd_send_sync_main(), assert on req type [Fabiano] - Some more comments and cleanup for RAM_SAVE_FLAG_* movement [Fabiano] - Update the last document patch [Fabiano] This series provides some changes that may be helpful for either VFIO or postcopy integration on top of multifd. For VFIO, only patches 1 & 2 are relevant. For postcopy, it's about patches 3-7, but it needs to be based on 1+2 because of a context dependency. All these patches can be seen as cleanups / slight optimizations on top of master branch with/without the VFIO/postcopy work. Besides CI, qtests, and some real-world multifd tests just to monitor the sync events happen all correct, I made sure to cover 7.2 machine type (which uses the legacy sync) so it still works as before - basically sync will be more frequent, but all thing keeps working smoothly so far.
