1d019736 - selftests: ublk: common: fix _get_disk_dev_t for pre-9.0 coreutils

Wed, 23 Apr 2025 21:00:00 +0000

selftests: ublk: common: fix _get_disk_dev_t for pre-9.0 coreutilsSome distributions, such as centos stream 9, still have a version ofcoreutils which does not yet support the %Hr and %Lr formats for stat(1)[1, 2]. Running ublk selftests on these distributions results in thefollowing 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 touse the much older %t and %T formats for stat instead.[1] https://github.com/coreutils/coreutils/blob/v9.0/NEWS#L114[2] https://pkgs.org/download/coreutilsSigned-off-by: Uday Shankar Reviewed-by: Ming Lei Link: https://lore.kernel.org/r/20250423-ublk_selftests-v1-2-7d060e260e76@purestorage.comSigned-off-by: Jens Axboe List of files: /linux-6.15/tools/testing/selftests/ublk/test_common.sh
