/******************************************************************************
- copy_file
*/ static BOOL copy_file( const WCHAR *source, const WCHAR *dest, COPYFILE2_EXTENDED_PARAMETERS *params )
The patch subject doesn't match what you're doing. Let's use "kernelbase: Limit the maximum path length for copy_file()."
