Mostly minor changes, bigger ones summarized: * QEMU's internal backup code now uses a new async system, which allows parallel requests - the default max_workers settings is 64, I chose less, since 64 put enough stress on QEMU that the guest became practically unusable during the backup, and 16 still shows quite a nice measureable performance improvement. Little code changes for us though. * 'malformed' QAPI parameters/functions are now a build error (i.e. using '_' vs '-'), I chose to just whitelist our calls in the name of backwards compatibility. * monitor OOB race fix now uses the upstream variant, cherry-picked from origin/master since it's not in 6.0 by default * last patch fixes a bug with snapshot rollback related to the new yank system Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
