Hi Steve,

Here are two patches for cifs:

 (1) 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.

 (2) Fix FICLONE which has the same set of bugs as (1).

I've pushed the patches here also:
