NFSD: handle GETATTR conflict with write delegation
If the GETATTR request on a file that has write delegation in effect
and the request attributes include the change info and size attribute
then the request is handled as below:
Server sends CB_GETATTR to client to get the latest change info and file
size. If these values are the same as the server's cached values then
the GETATTR proceeds as normal.
If either the change info or file size is different from the server's
cached values, or the file was already marked as modified, then:
. update time_modify and time_metadata into file's metadata
with current time
. encode GETATTR as normal except the file size is encoded with
the value returned from CB_GETATTR
. mark the file as modified
If the CB_GETATTR fails for any reasons, the delegation is recalled
and NFS4ERR_DELAY is returned for the GETATTR.
