Fabiano Rosas 8fa1a21c6e migration/multifd: Fix clearing of mapped-ram zero pages ... When the zero page detection is done in the multifd threads, we need to iterate the second part of the pages->offset array and clear the file bitmap for each zero page. The piece of code we merged to do that is wrong. The reason this has passed all the tests is because the bitmap is initialized with zeroes already, so clearing the bits only really has an effect during live migration and when a data page goes from having data to no data. Fixes: 303e6f54f9 ("migration/multifd: Implement zero page transmission on the multifd thread.")
