v2: - Measure packet size in bytes/not pages - Change the defalut value from 64KB to 512KB - rename used field to pages_used - rename size field to pages_alloc - Create nnext_packet_size field Will be used on compression series later. - Be flexible about what packet sizes we allow.
Please review, In v1: - Change page_count default to 128. 16 was really small, and it makes much less contention on mutexes to just have bigger packets. - Drop multifd-page_count parameter This parameter was useful for testing, but in all my testing 128 is good enough, no need to have an extra knob. Libvirt don't want to expose this parameter because it is difficult to explain. - Drop experimental "x-" from multifd Code is stable, nothing big is happening here. - Multifd test And a test for multifd, this test has already been on other patch series. But now it uses the names without "-x". Please review.
