Good point, thanks! -D is still used, but in less C tests.

$ git grep '"D:"' $(git grep -l tst_option)
testcases/kernel/syscalls/ioctl/ioctl02.c:              {"D:", &device, "Tty device. For example, /dev/tty[0-9]"},
testcases/network/can/filter-tests/can_filter.c:                {"D:", &can_dev_name, "CAN device name"},
testcases/network/can/filter-tests/can_rcv_own_msgs.c:          {"D:", &can_dev_name, "CAN device name"},
testcases/network/netstress/netstress.c:                {"D:", &dev, "Bind to device x"},

But at least -D is not used in shell.
$ git grep "TST_OPTS=.*D"

Kind regards,
Petr
