2022-04-10selftests/bpf: Improve by-name subtest selection logic in prog_testsMykola Lysenko1-0/+107
Improve subtest selection logic when using -t/-a/-d parameters. In particular, more than one subtest can be specified or a combination of tests / subtests. -a send_signal -d send_signal/send_signal_nmi* - runs send_signal test without nmi tests -a send_signal/send_signal_nmi*,find_vma - runs two send_signal subtests and find_vma test -a 'send_signal*' -a find_vma -d send_signal/send_signal_nmi* - runs 2 send_signal test and find_vma test. Disables two send_signal nmi subtests -t send_signal -t find_vma - runs two *send_signal* tests and one *find_vma* test This will allow us to have granular control over which subtests to disable in the CI system instead of disabling whole tests. Also, add new selftest to avoid possible regression when changing prog_test test name selection logic.
