Subject: [PATCH v2 0/7] Handle faults in KUnit tests

Hi,

This patch series teaches KUnit to handle kthread faults as errors, and
it brings a few related fixes and improvements.

I removed the previous patch that moved the KUnit test execution at the
very end of kernel initialization.  We'll address that with a separate
series.

A new test case check NULL pointer dereference, which wasn't possible
before.

This is useful to test current kernel self-protection mechanisms or
future ones such as Heki: https://github.com/heki-linux

Previous version:
v1: https://lore.kernel.org/r/20240229170409.365386-1-mic@digikod.net

Regards,

Mickaël Salaün (7):
  kunit: Handle thread creation error
  kunit: Fix kthread reference
  kunit: Fix timeout message
  kunit: Handle test faults
  kunit: Fix KUNIT_SUCCESS() calls in iov_iter tests
  kunit: Print last test location on fault
  kunit: Add tests for fault
