According to kselftest.h ksft_exit_skip() is not meant to be called when a plan has already been printed.
Use the recommended function ksft_test_result_skip().
This fixes a bug, where the TAP output would be invalid when skipping:
TAP version 13 1..1 ok 2 # SKIP Not implemented on architecture
The SKIP line should start with "ok 1" as the plan only contains one test.
Fixes: 3b5992eaf730 ("selftests: vDSO: unconditionally build chacha test") Reviewed-by: Muhammad Usama Anjum usama.anjum@collabora.com Signed-off-by: Thomas Weißschuh thomas.weissschuh@linutronix.de --- I'm not sure if this is not a general bug in ksft_exit_skip(). First ksft_xskip is incremented then read back through ksft_test_num() and then that result is incremented again.
In any case, using the correct function is better. --- tools/testing/selftests/vDSO/vdso_test_chacha.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
