NFSv4: Define an fs_locations bitmap
This is (similar to getattr bitmap) but includes fs_locations and mounted_on_fileid attributes. Use this bitmap for encoding in fs_locations requests. Note: We can probably do better by requesting locations as part of fsinfo itself. Signed-off-by: Manoj Naik <manoj@almaden.ibm.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
