This patchset contains everything needed to integrate KASAN and KUnit.

KUnit will be able to:
(1) Fail tests when an unexpected KASAN error occurs
(2) Pass tests when an expected KASAN error occurs

KASAN Tests have been converted to KUnit with the exception of
copy_user_test because KUnit is unable to test those. I am working on
documentation on how to use these new tests to be included in the next
version of this patchset.

Changes since v1:
 - Make use of Alan Maguire's suggestion to use his patch that allows
   static resources for integration instead of adding a new attribute to
   the kunit struct
 - All KUNIT_EXPECT_KASAN_FAIL statements are local to each test
 - The definition of KUNIT_EXPECT_KASAN_FAIL is local to the
   test_kasan.c file since it seems this is the only place this will
   be used.
 - Integration relies on KUnit being builtin
 - copy_user_test has been separated into its own file since KUnit
   is unable to test these. This can be run as a module just as before,
   using CONFIG_TEST_KASAN_USER
 - The addition to the current task has been separated into its own
   patch as this is a significant enough change to be on its own.

Patricia Alfonso (3):
  Add KUnit Struct to Current Task
  KUnit: KASAN Integration
  KASAN: Port KASAN Tests to KUnit
