59afac32fe - get pages to loan out in uvm_loanuobjpages() rather than
having caller (nfsd, in this case) do so.
- tweak locking so that nfs loaned READ works on layered filesystems.

2ef662a69e Clean up the usage of vn_start_write(). At least one occurence clobbered
previous error conditions.
If "(flags & (V_WAIT|V_PCATCH)) == V_WAIT" the return value is always zero.
Ignore the return value in these cases.

a3a898ff0f Add the gating of system calls that cause modifications to the underlying
file system.
The function vfs_write_suspend stops all new write operations to a file
system, allows any file system modifying system calls already in progress
to complete, then sync's the file system to disk and returns. The
function vfs_write_resume allows the suspended write operations to
complete.

From FreeBSD with slight modifications.

a678ebca13 nfsrv_commit(): return success and don't do anything for requests which starts
past the end of the file. This can happen when two clients are writting to
the same file.
Close PR 21696 by myself, discussed on tech-net in 2003/05 and 2003/06.
Issue raised by Chuck Silvers (commit and truncate ops needs to be serialised)
still unadressed.

d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,

a06b275edc Undo part of the ktrace/lwp changes. In particular:
* Remove the "lwp *" argument that was added to vget().  Turns out
  that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
  and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
  above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
  just to appease the above.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

9c329a66d1 rework zero padding of rpc reply.
- for READ procedure, don't send back more bytes than requested.
- don't have doubtful assumptions on mbuf chain structure.
- rename a function (nfsm_adj -> nfs_zeropad) to avoid confusion as
  the semantics of the function was changed.

85d0052723 workaround for UBC limit.
while our nfsd announces MAXBSIZE as wtmax for tcp,
VOP_GETPAGES of filesystems that uses genfs_getpages can't
handle >= MAX_READ_AHEAD(16) pages at once.
therefore, depending on PAGE_SIZE of the machine and file offset of
a read request, we can't VOP_GETPAGES the range at once.

65e5548a17 Add MBUFTRACE kernel option.
Do a little mbuf rework while here.  Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *).  These are not performance critical and making them
call m_get saves considerable space.  Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.

1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

* Split flags for internal and external use in the NFS mount structure.
* Fix some buffer structure fields that weren're being used correctly.
* Fix missing directory cache inval call in nfs_open.
* Limit on NFS_DIRBLKSIZ no longer needed, bumped to the more reasonable
  value of 8k.
* Various other things that I forget, all related to the dir caching
  somehow, though.
