Yuan Liu 5ef7e26bdb migration/multifd: solve zero page causing multiple page faults ... Implemented recvbitmap tracking of received pages in multifd. If the zero page appears for the first time in the recvbitmap, this page is not checked and set. If the zero page has already appeared in the recvbitmap, there is no need to check the data but directly set the data to 0, because it is unlikely that the zero page will be migrated multiple times.
