    Merge branch 'iomap-write' into linux-gfs2/for-next · a3479c7f

    Pull in the gfs2 iomap-write changes: Tweak the existing code to
    properly support iomap write and eliminate an unnecessary special case
    in gfs2_block_map.  Implement iomap write support for buffered and
    direct I/O.  Simplify some of the existing code and eliminate code that
    is no longer used:
    
      gfs2: Remove gfs2_write_{begin,end}
      gfs2: iomap direct I/O support
      gfs2: gfs2_extent_length cleanup
      gfs2: iomap buffered write support
      gfs2: Further iomap cleanups
    
    This is based on the following changes on the xfs 'iomap-4.19-merge'
    branch:
    
      iomap: add private pointer to struct iomap
      iomap: add a page_done callback
      iomap: generic inline data handling
      iomap: complete partial direct I/O writes synchronously
      iomap: mark newly allocated buffer heads as new
      fs: factor out a __generic_write_end helper
