[Qemu-devel] [PATCH 1/5] Support for vm_stop from the migration thread

[Umesh Deshpande]

Currently, when any thread other than iothread calls vm_stop, it is scheduled to
be executed later by the iothread. This patch allows the execution of vm_stop
from threads other than iothread. This is especially helpful when the migration 
is
moved into a separate thread.
