Modified files:
sys/vm vm_fault.c vm_page.c
Log:
Complete the page queues locking needed for the page-based copy-
on-write (COW) mechanism. (This mechanism is used by the zero-copy
TCP/IP implementation.)
- Extend the scope of the page queues lock in vm_fault()
to cover vm_page_cowfault().
- Modify vm_page_cowfault() to release the page queues lock
if it sleeps.
