History
Alan Cox d5efa0a475 Switching from a global hash table to per-vm_object radix tries for mapping 
vm_object page indices to on-disk swap space (r322913) has changed the
synchronization requirements for a couple swap pager functions.  Whereas
before a read lock on the vm object sufficed because of the global mutex
on the hash table, a write lock on the vm object may now be required.  In
particular, calls to vm_pager_page_unswapped() now require a write lock on
the vm_object.  Consequently, vm_fault()'s fast path cannot call
vm_pager_page_unswapped().  The swap space will have to be released at a
later point.
