The userspace component attempts to do this, but this will prevent
us from even needing to go into userspace to satisfy certain getattr
requests.

Previously the client-core detected this condition by sheer luck!
Since we used strncpy, no NUL byte would be included on the name. The
client-core would call strlen, which would read past the end of its
buffer, but return a number large enough that the client-core would
return ENAMETOOLONG.

Thus d_revalidate is not obliged to check on as much, which will
eventually lead the way to hammering the filesystem servers much less.

OrangeFS was formerly known as PVFS2 and retains the name in many places.
I leave the device /dev/pvfs2-req since this affects userspace.
I leave the filesystem type pvfs2 since this affects userspace. Further
the OrangeFS sysint library reads fstab for an entry of type pvfs2
independently of kernel mounts.
I leave extended attribute keys user.pvfs2 and system.pvfs2 as the
sysint library understands these.
I leave references to userspace binaries still named pvfs2.
I leave the filenames.
