This patch addresses:

 - a potential data inconsistency that can occur when a CFS
   client reads a file that was recently written to.
   Stale data can be returned to the client.

 - multi-volume AdvFS v3 domains reporting:

      - EIO errors (not attributable to hardware)

        For example, if a second volume is added to an existing 
        domain and the first volume then becomes 100% full, every 
        other file or directory creation will fail from then on:
             # cp /vmunix /test/file1
             cp: /test/file1: I/O error
             # mkdir teste5
             # mkdir teste6
             mkdir: cannot create teste6.
             teste6: I/O error

      - ENO_XTNTS error on failed mkfset

        If the domain is made multi-volume prior to creating
        a fileset then the mkfset command will fail:
             # mkfdmn -V 3 /dev/disk/dsk1a test
             # addvol /dev/disk/dsk1b test
             # mkfset test 1
             mkfset: can't create file set '1' in domain 'test'
             mkfset: error = ENO_XTNTS (-1036)
