Hi Steve,

Here are three patches for cifs:

 (1) Fix FALLOC_FL_ZERO_RANGE support to change i_size if the file is
     extended.

 (2) Fix FALLOC_FL_INSERT_RANGE support to change i_size after it moves the
     EOF on the server.

 (3) Fix copy_file_range() support to handle invalidation and flushing of
     overlapping dirty data correctly, to move the EOF on the server to
     deal with lazy flushing of locally dirty data and to set the i_size
     afterwards if the copy extended the file.

I've pushed the patches here also:
