NFS incorrectly update atime

[Rong-en Fan]

Hi,

  I'm using FreeBSD 4.8-RELEASE for both NFS server and client,
  however when i append file from client, it updates both
  atime and mtime, where atime shouldn't be updated.

$ touch testfile
$ stat testfile
Access: Thu Sep 25 01:17:43 2003
Modify: Thu Sep 25 01:17:43 2003
Change: Thu Sep 25 01:17:43 2003
$ echo foobar >> testfile
$ stat testfile
Access: Thu Sep 25 01:17:43 2003
Modify: Thu Sep 25 01:19:15 2003
Change: Thu Sep 25 01:19:15 2003
$ echo foobar >> testfile
$ stat testfile
Access: Thu Sep 25 01:19:31 2003
Modify: Thu Sep 25 01:19:31 2003
Change: Thu Sep 25 01:19:31 2003

  it only occur when file is not empty, also i've noticed that
  http://www.freebsd.org/cgi/query-pr.cgi?pr=44580
  is the same problem. BTW, i also test it on 5.1-RELEASE,
  and got the same result.

  btw, i don't subscribe this mailing, so please CC me thanks :)
