    afs: Reorganise volume and server trees to be rooted on the cell · 20325960
    David Howells authored
    Reorganise afs_volume objects such that they're in a tree keyed on volume
    ID, rooted at on an afs_cell object rather than being in multiple trees,
    each of which is rooted on an afs_server object.
    
    afs_server structs become per-cell and acquire a pointer to the cell.
    
    The process of breaking a callback then starts with finding the server by
    its network address, following that to the cell and then looking up each
    volume ID in the volume tree.
    
    This is simpler than the afs_vol_interest/afs_cb_interest N:M mapping web
    and allows those structs and the code for maintaining them to be simplified
    or removed.
    
    It does make a couple of things a bit more tricky, though:
    
     (1) Operations now start with a volume, not a server, so there can be more
         than one answer as to whether or not the server we'll end up using
         supports the FS.InlineBulkStatus RPC.
    
     (2) CB RPC operations that specify the server UUID.  There's still a tree
         of servers by UUID on the afs_net struct, but the UUIDs in it aren't
         guaranteed unique.
