- constify genfs_ops.
- use member designators.

        sys/miscfs/genfs/genfs_vnops.c: revision 1.99 via patch
genfs_getpages: don't forget to put the vnode onto the syncer's work que
ue
even in the case of PGO_LOCKED.

        sys/uvm/uvm_bio.c: revision 1.40
        sys/uvm/uvm_pager.h: revision 1.29
        sys/miscfs/genfs/genfs_vnops.c: revision 1.100 via patch
        sys/ufs/ufs/ufs_inode.c: revision 1.50
- introduce PGO_NOBLOCKALLOC and use it for ubc mapping
  to prevent unnecessary block allocations in the case that
  page size > block size.
- ufs_balloc_range: use VM_PROT_WRITE+PGO_NOBLOCKALLOC rather than
  VM_PROT_READ.

        sys/uvm/uvm_fault.c: revision 1.96
        sys/miscfs/genfs/genfs_vnops.c: revision 1.101 via patch
        sys/uvm/uvm_object.h: revision 1.19
        sys/miscfs/genfs/genfs_node.h: revision 1.7
ensure that vnodes with dirty pages are always on syncer's queue.
- genfs_putpages: wait for i/o completion of PG_RELEASED/PG_PAGEOUT pages by
  setting "wasclean" false when encountering them.
  suggested by Stephan Uphoff in PR/24596 (1).
- genfs_putpages: write protect pages when cleaning out, if
  we're going to take the vnode off the syncer's queue.
  uvm_fault: don't write-map pages unless its vnode is already on
  the syncer's queue.
  fix PR/24596 (3) but in the different way from the suggested fix.
  (to keep our current behaviour, ie. not to require explicit msync.
  discussed on tech-kern@.)
- genfs_putpages: don't mistakenly take a vnode off the queue
  by introducing a generation number in genfs_node.
  genfs_getpages: increment the generation number.
  suggested by Stephan Uphoff in PR/24596 (2).
- add some assertions.

        sys/miscfs/genfs/genfs_vnops.c: revision 1.102 via patch
genfs_putpages: don't bother to clean the vnode unless VONWORKLST.

        sys/ufs/ffs/ffs_vnops.c: revision 1.71
ffs_full_fsync: because VBLK/VCHR can be mmap'ed,
do VOP_PUTPAGES for them as well.

        sys/uvm/uvm_fault.c: revision 1.97
uvm_fault: check a correct object in the case of layered filesystems.
fix PR/30811 from Jukka Salmi.

update file timestamps for nfsd loaned-read and mmap.
PR/25279.  discussed on tech-kern@.

        sys/miscfs/genfs/genfs_vnops.c: revision 1.104 via patch
don't write-protect wired pages.  pointed by Chuck Silvers.
for now, leave a vnode on the syncer's queue, as suggested by him.

        sys/ufs/ffs/ffs_vnops.c: revision 1.72
revert VCHR part of ffs_vnops.c 1.71.
as VCHR uses the device pager, no point to call VOP_PUTPAGES here.
pointed by Chuck Silvers.
