Fix thinko that, with two map entries like shown below, in that order,
made autofs mix them up: the second one wasn't visible in ls(1) output,
and trying to access it would trigger mount for the first one.

foobar          host:/foobar
foo             host:/foo

There are still a few outstanding problems; they will be fixed shortly.

The new NFSv3 server did not generate directory postop attributes for
the reply to ReaddirPlus when the server failed within the loop
that calls VFS_VGET(). This failure is most likely an error
return from VFS_VGET() caused by a bogus d_fileno that was
truncated to 32bits.
This patch fixes the server so that it will return directory postop
attributes for the failure. It does not fix the underlying issue caused
by d_fileno being uint32_t when a file system like ZFS generates
a fileno that is greater than 32bits.

Merge the NFSv4.1 server code in projects/nfsv4.1-server over

on the semantics of non-NFSv4.1 server behaviour.
It is a rather large merge, but I am hoping that there will

There might be a potential race condition for the NFSv4 client
when a newly created file has another open done on it that
update the open mode. This patch moves the code that updates
the open mode up into the block where the mutex is held to
ensure this cannot happen. No bug caused by this potential
race has been observed, but this fix is a safety belt to ensure
it cannot happen.

The new NFS server would not allow a hard link to be
created to a symlink. This restriction (which was
inherited from OpenBSD) is not required by the NFS RFCs.
Since this is allowed by the old NFS server, it is a
POLA violation to not allow it. This patch modifies the
new NFS server to allow this.

The new draft specification for NFSv4.0 specifies that a server
should either accept owner and owner_group strings that are just
the digits of the uid/gid or return NFS4ERR_BADOWNER.
This patch adds a sysctl vfs.nfsd.enable_stringtouid, which can
be set to enable the server w.r.t. accepting numeric string. It
also ensures that NFS4ERR_BADOWNER is returned if numeric uid/gid
strings are not enabled. This fixes the server for recent Linux
nfs4 clients that use numeric uid/gid strings by default.
