Konstantin Belousov 99a1570a25 r221714 fixed the situation when the collapse scan improperly handled ... invalid (busy) page supposedly inserted by the vm_fault(), in the OBSC_COLLAPSE_NOWAIT case. As a continuation to r221714, fix a case when invalid page is found by the object scan in OBSC_COLLAPSE_WAIT case as well. But, since this is waitable scan, we should wait for the termination of the busy state and restart from the beginning of the backing object' page queue. [*] Do not free the shadow page swap space when the parent page is invalid, otherwise this action potentially corrupts user data. Combine all instances of the collapse scan sleep code fragments into the new helper vm_object_backing_scan_wait(). Improve style compliance and comments. Change the return type of vm_object_backing_scan() to bool.
