From: Giuseppe Musacchio <thatlemon@gmail.com> An unwanted sign-extension is currently making the host kernel return EOVERFLOW when calling copy_file_range with a count of 0xffffffff, despite the host being a 64bit platform. The fix is only affecting 32bit targets on 64bit hosts, it's a no-op when the target bitness matches the host one. As a bonus add a pretty-printer for copy_file_range syscall.
