Some distributions, such as centos stream 9, still have a version of coreutils which does not yet support the %Hr and %Lr formats for stat(1) [1, 2]. Running ublk selftests on these distributions results in the following error in tests that use the _get_disk_dev_t helper: line 23: ?r: syntax error: operand expected (error token is "?r") To better accommodate older distributions, rewrite _get_disk_dev_t to use the much older %t and %T formats for stat instead.
