fvdl 0b1963121a Add Kirk McKusick's soft updates code to the trunk. Not enabled by
default, as the copyright on the main file (ffs_softdep.c) is such
that is has been put into gnusrc. options SOFTDEP will pull this
in. This code also contains the trickle syncer.

Bump version number to 1.4O

wrstuden 092a6ee985 Since we don't put layered device nodes in the spechash hash chains,
initialize vp->v_hashchain to NULL.

fvdl d369311766 Remove some mentioned members in the vop {un}lock args struct that we
do not actually have.

wrstuden 3bf14d81e9 Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl
call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

wrstuden a0f2937049 Define VLAYER and make layered fs's set this flag when creating their vnodes.
getnewvnode now checks this bit, and it if's set makes sure a vnode's not
locked before removing it from the free list.

Closes PR 7954 by Alan Barrett <apb@iafrica.com>.

wrstuden 9866514df5 Introduce layer library in genfs. This set of files abstracts most of
the functionality of nullfs. The latter is now just a mount & unmount
routine, and a few tables. umapfs borrow most of this infrastructure.

Both fs's are now nfs-exportable.

All layered fs's share a common format to private mount & private
vnode structs (which a particular fs can extend).

Also add genfs_noerr_rele(), a vnode op which will vrele/vput
operand vnodes appropriately.

thorpej 961f0708b1 - Rename nqnfs_vop_lease_check() to genfs_lease_check(). If NFSSERVER is
not in the kernel, genfs_lease_check() is simply a no-op.  This allows
  LKM'd file systems to be exported (previously did not work properly
  due to a compile-time decision based on -DNFSSERVER).

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

kleink a32a338757 * Convert fsync vnode operator implementations and usage from the old
waitfor argument and MNT_WAIT/MNT_NOWAIT to flags and FSYNC_WAIT.
* In genfs_fsync(), honor the FSYNC_NODATA flag.
