[Message part 1 (text/plain, inline)]

Sorry, this is new patch, I fix a bug.

The `rename` function, if trying to rename a file across filesystem or 
device, it's not work, and give the EXDEV erorr:

    Invalid cross-device link

So, I add a new function `do_move_file`: if the rename fails, copy a new 
file, and unlink source file.
