Some testcases may require a special rename flag, such as RENAME_WHITEOUT, so add support check for if a given rename flag is supported in _require_renameat2. [Eryu: rename the helper to _require_renameat2 while we're at it, and add 'exchange' check to generic/398 and generic/419] Signed-off-by: kaixuxia <kaixuxia@tencent.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
