    sys/fs/nwfs          nwfs_io.c 
    sys/fs/smbfs         smbfs_io.c 
    sys/kern             uipc_syscalls.c vfs_bio.c

                         vm_page.h vnode_pager.c 
  Log:
  Introduce a field to struct vm_page for storing flags that are
  synchronized by the lock on the object containing the page.
  
  Transition PG_WANTED and PG_SWAPINPROG to use the new field,
  eliminating the need for holding the page queues lock when setting
  or clearing these flags.  Rename PG_WANTED and PG_SWAPINPROG to
  VPO_WANTED and VPO_SWAPINPROG, respectively.
  
  Eliminate the assertion that the page queues lock is held in
  vm_page_io_finish().
  
  Eliminate the acquisition and release of the page queues lock
  around calls to vm_page_io_finish() in kern_sendfile() and
  vfs_unbusy_pages().
