-Subject: kunit: Handle test faults
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Mickaël Salaün <mic@digikod.net>
-
-[ Upstream commit 3a35c13007dea132a65f07de05c26b87837fadc2 ]
-
-Previously, when a kernel test thread crashed (e.g. NULL pointer
-dereference, general protection fault), the KUnit test hanged for 30
-seconds and exited with a timeout error.
-
-Fix this issue by waiting on task_struct->vfork_done instead of the
-custom kunit_try_catch.try_completion, and track the execution state by
-initially setting try_result with -EINTR and only setting it to 0 if
-the test passed.
-
-Fix kunit_generic_run_threadfn_adapter() signature by returning 0
-instead of calling kthread_complete_and_exit(). Because thread's exit
-code is never checked, always set it to 0 to make it clear. To make
-this explicit, export kthread_exit() for KUnit tests built as module.
-
-Fix the -EINTR error message, which couldn't be reached until now.
-
-This is tested with a following patch.

-Subject: kunit: Handle test faults
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Mickaël Salaün <mic@digikod.net>
-
-[ Upstream commit 3a35c13007dea132a65f07de05c26b87837fadc2 ]
-
-Previously, when a kernel test thread crashed (e.g. NULL pointer
-dereference, general protection fault), the KUnit test hanged for 30
-seconds and exited with a timeout error.
-
-Fix this issue by waiting on task_struct->vfork_done instead of the
-custom kunit_try_catch.try_completion, and track the execution state by
-initially setting try_result with -EINTR and only setting it to 0 if
-the test passed.
-
-Fix kunit_generic_run_threadfn_adapter() signature by returning 0
-instead of calling kthread_complete_and_exit(). Because thread's exit
-code is never checked, always set it to 0 to make it clear. To make
-this explicit, export kthread_exit() for KUnit tests built as module.
-
-Fix the -EINTR error message, which couldn't be reached until now.
-
-This is tested with a following patch.
