generic: test reflink and copy_file_range behavior with O_SYNC and FS_XFLAG_SYNC files
Add two regression tests to make sure that FICLONERANGE and the splice based copy_file_range actually flush all data and metadata to disk before the call ends. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Chandan Babu R <chandanrlinux@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
