    NFS: Generalise the nfs_client structure · 24c8dbbb
    David Howells 提交于
    Generalise the nfs_client structure by:
    
     (1) Moving nfs_client to a more general place (nfs_fs_sb.h).
    
     (2) Renaming its maintenance routines to be non-NFS4 specific.
    
     (3) Move those maintenance routines to a new non-NFS4 specific file (client.c)
         and move the declarations to internal.h.
    
     (4) Make nfs_find/get_client() take a full sockaddr_in to include the port
         number (will be required for NFS2/3).
    
     (5) Make nfs_find/get_client() take the NFS protocol version (again will be
         required to differentiate NFS2, 3 & 4 client records).
    
    Also:
    
     (6) Make nfs_client construction proceed akin to inodes, marking them as under
         construction and providing a function to indicate completion.
    
     (7) Make nfs_get_client() wait interruptibly if it finds a client that it can
         share, but that client is currently being constructed.
    
     (8) Make nfs4_create_client() use (6) and (7) instead of locking cl_sem.
