Subject: do not use timedwait on qemu_pause_cond
X-Git-Tag: v2.7.1~7168
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=be7d6c57c4598ca9fcb3f6fbe57c13110ebd6c70;p=mirror_qemu.git

do not use timedwait on qemu_pause_cond

all_vcpus_paused can start returning true after penv->stopped changes
from 0 to 1.  When this is done, qemu_pause_cond is always signaled.
