vop_stdallocate() is filesystem agnostic and will run as slow as a
read/write loop in userspace; however, it serves to correctly
implement the functionality for filesystems that do not implement a
VOP_ALLOCATE.
Note that __FreeBSD_version was already bumped today to 900036 for any
ports which would like to use this function.
Also reserve space in the syscall table for posix_fadvise(2).

for a case that will probably never happen. It can only
happen if a server were to successfully lookup a file, but not
return attributes for that file. Although technically allowed
by the NFSv3 RFC, I doubt any server would ever do this.
However, if it did, the client would have not vput()'d the
new vnode when it needed to do so.

that would be needed if, in the future, nfscl_loadattrcache()
were to return an error. Currently nfscl_loadattrcache()
never returns an error, so these cases never currently happen.

experimental NFS client's vnode op functions to make
them compatible with the regular NFS client. I'll admit
I'm not sure that the mutex locks around the assignments
are needed, but the regular client has them, so I added them.
Also, add handling of the case of partial attributes in
setattr to be compatible with the regular client.

functions, so that threads don't get stuck in them during
a forced dismount. nfs_sync/VFS_SYNC() needs this, since it is
called by dounmount() before VFS_UNMOUNT(). The nfscl_nget()
case makes sure that a thread doing an VOP_OPEN() or
VOP_ADVLOCK() call doesn't get blocked before attempting
the RPC. Attempting RPCs don't block, since they all
fail once a forced dismount is in progress.
The third one at the beginning of nfsrpc_close()
is done so threads don't get blocked while doing VOP_INACTIVE()
as the vnodes are cleared out.
With these three changes plus a change to the umount(1)
command so that it doesn't do "sync()" for the forced case
seem to make forced dismounts work for the experimental NFS
client.

that is running even though not _enable'd had an annoying side effect.
If the service was already started at boot time by another means when
the related script came around again in rcorder it would start again,
regardless of _enable, because there was a valid pid. [1]
So, split the test into 2 parts, one for (!rcvar && !stop), and one
for (stop && !valid_pid). This preserves the behavior from r206686
while preventing the undesired side effect.

message that was generated when doing experimental NFS client
mounts. I put that message in because the krpc would hang with
the default size for mounts that used large rsize/wsize values.
Since the bug that caused these hangs was fixed by r213756,
I think the message is no longer needed.

While it does not provide any functionality for IPv6, it provides
the sysctl nodes for net.inet.* that a lot of functionality shared
between IPv4 and IPv6 depends on. We cannot change these anymore
without breaking a lot of management and tuning.
In case of IPv6 only, we compile out everything but the sysctl node
declarations.

If various checks are omitted, the CMSG_NXTHDR macro expands to
(struct cmsghdr *)((char *)(cmsg) + \
_ALIGN(((struct cmsghdr *)(cmsg))->cmsg_len))
Although there is no alignment problem (assuming cmsg is properly aligned
and _ALIGN is correct), this violates -Wcast-align on strict-alignment
architectures. Therefore an intermediate cast to void * is appropriate here.
There is no workaround other than not using -Wcast-align.

The code provides information on how the signal was generated.
Formerly, the code was only logged for traps, much like only signal handlers
for traps received a meaningful si_code before FreeBSD 7.0.
In rare cases, no information is available and 0 is still logged.
