[PATCH 0/2] migration/multifd: Fix rb->receivedmap cleanup race

Posted by Fabiano Rosas 2 months, 1 week ago

This fixes the crash we've been seing recently in migration-test. The
first patch is a cleanup to have only one place calling
qemu_loadvm_state_cleanup() and the second patch reorders the cleanup
calls to make multifd_recv_cleanup() run first and stop the recv
threads.
