Subject: [GIT PULL] Kunit next update for Linux 5.10-rc1

Hi Linus,

Please pull the following Kunit next update for Linux 5.10-rc1.

This Kunit update for Linux 5.10-rc1 consists of:

- add Kunit to kernel_init() and remove KUnit from init calls entirely.
   This addresses the concern Kunit would not work correctly during
   late init phase.
- add a linker section where KUnit can put references to its test
   suites.
   This patch is the first step in transitioning to dispatching all KUnit
   tests from a centralized executor rather than having each as its own
   separate late_initcall.
- add a centralized executor to dispatch tests rather than relying on
   late_initcall to schedule each test suite separately. Centralized
   execution is for built-in tests only; modules will execute tests when
   loaded.
- convert bitfield test to use KUnit framework
- Documentation updates for naming guidelines and how kunit_test_suite()
   works.
- add test plan to KUnit TAP format

diff is attached.

Please note that there is a conflict in lib/kunit/test.c

between commit:

   45dcbb6f5ef7 ("kunit: test: add test plan to KUnit TAP format")

from the kunit-next tree and commit:

e685acc91080 ("KUnit: KASAN Integration")

from the akpm-current tree. (now in master)

Stephen fixed this up in linux-next. Please let me know if you run
into any problems.

thanks,
-- Shuah
