[PATCH v3 1/7] kunit: Handle thread creation error
From: Mickaël Salaün
Date: Tue Mar 19 2024 - 06:56:03 EST
Previously, if a thread creation failed (e.g. -ENOMEM), the function was
called (kunit_catch_run_case or kunit_catch_run_case_cleanup) without
marking the test as failed. Instead, fill try_result with the error
code returned by kthread_run(), which will mark the test as failed and
print "internal error occurred...".
