Subject: [nfsv4] rigged attributes








NFSv3 discusses filesystems which do not support the storing of some NFS
attributes on nonvolatile storage.  An example of the server assigning
CTIME=MTIME is provided if CTIME is not hardened.  We have file systems
which only stores create time, while others only store modified time.  With
the introduction of the v4 attribute mask, is it expected the server will
no longer return server generated attributes and let the client make the
more intelligent decision of determining a value for client applications?

note: in a cross mount environment, if the client PFS layer generates attrs
which are returned to a nfs server VFS layer, the server will not remove
these dummy attributes.


Thanks,
Stevan C. Allen
