[Qemu-devel] [resend][PATCH] qga: unset frozen state if no mount points are frozen

Posted by Chen Hanxiao 36 weeks ago
From: Chen Hanxiao <chenhanxiao@gmail.com>

If we set mountpoints to qmp_guest_fsfreeze_freeze_list,
we may got nothing to freeze as all mountpoints are
not valid.
Call ga_unset_frozen in this senario.
