Subject: migration/multifd: Remove unnecessary assignment on multifd_load_cleanup()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d926f3bb2a84fdb746678629279a143f568c3c86;p=qemu.git

migration/multifd: Remove unnecessary assignment on multifd_load_cleanup()

Before assigning "p->quit = true" for every multifd channel,
multifd_load_cleanup() will call multifd_recv_terminate_threads() which
already does the same assignment, while protected by a mutex.

So there is no point doing the same assignment again.
