CIFS: Fix SMB2/SMB3 Copy offload support (refcopy) for large files This third version of the patch, incorparating feedback from David Disseldorp extends the ability of copychunk (refcopy) over smb2/smb3 mounts to handle servers with smaller than usual maximum chunk sizes and also fixes it to handle files bigger than the maximum chunk sizes In the future this can be extended further to handle sending multiple chunk requests in on SMB2 ioctl request which will further improve performance, but even with one 1MB chunk per request the speedup on cp is quite large.
