+Basically a version of C<aio_rename> with an additional C<$flags>
+argument. Calling this with C<$flags=0> is the same as calling
+C<aio_rename>.
+
+Non-zero flags are currently only supported on GNU/Linux systems that
+support renameat2. Other systems fail with C<ENOSYS> in this case.
+
+The following constants are available (missing ones are, as usual C<0>),
+see renameat2(2) for details:
+
+C<IO::AIO::RENAME_NOREPLACE>, C<IO::AIO::RENAME_EXCHANGE>
+and C<IO::AIO::RENAME_WHITEOUT>.
