now xfstests has not cover the senario that copy in same file related bug: copy_file_range return "Invalid argument" when copy in the same file https://bugzilla.kernel.org/show_bug.cgi?id=202935 step1: copy whole file to itself, and compare with original file. step2: copy whole file to end of itself, and compare the two halves with the original file step3: recover from original file.
