Changes in v3:
- Removed useless KSFT_PASS, KSFT_FAIL, KSFT_SKIP constants
- Used ktap_finished to print the results summary and handle the return code
Changes in v2:
- Added missing SPDX line
- Edited test_probe_samples.sh script to use the common KTAP helpers file

Looks good to me. Don't you need a config file for this test?
Refer to config files for existing tests as a reference.

On Linux 6.8-rc5 give the following? Doesn't look right.
  
TAP version 13
1..1
# timeout set to 45
# selftests: rust: test_probe_samples.sh
# ./test_probe_samples.sh: line 12: /linux/linux_6.8/tools/testing/selftests/rust/../kselftest/ktap_helpers.sh: No such file or directory
# ./test_probe_samples.sh: line 16: ktap_print_header: command not found
# ./test_probe_samples.sh: line 18: ktap_set_plan: command not found

not ok 1 selftests: rust: test_probe_samples.sh # exit=127

Right, in order for the tests to not be skipped support for rust and its
sample modules need to be enabled.

I added the config file in v4: https://lore.kernel.org/linux-kselftest/20240226101646.291337-1-laura.nao@collabora.com/T/#u

This patch requires
https://lore.kernel.org/all/20240102141528.169947-1-laura.nao@collabora.com/T/#u
and
https://lore.kernel.org/all/20240131-ktap-sh-helpers-extend-v1-0-98ffb468712c@collabora.com/
, which are both scheduled for 6.9-rc1. Sorry I didn't mention it above!

Thanks,
