  "message": "kunit: move call to kunit_run_all_tests() after rcu_end_inkernel_boot()\n\nGuenter Roeck reports that the new slub kunit tests added by commit\n4e1c44b3db79 (\"kunit, slub: add test_kfree_rcu() and\ntest_leak_destroy()\") cause a lockup on boot on several architectures\nwhen the kunit tests are configured to be built-in and not modules.\n\nThese tests invoke kfree_rcu() and kvfree_rcu_barrier() and boot\nsequence inspection showed the runner for built-in kunit tests\nkunit_run_all_tests() is called before setting system_state to\nSYSTEM_RUNNING and calling rcu_end_inkernel_boot(), so this seems like a\nlikely cause. So while I was unable to reproduce the problem myself,\nmoving the call to kunit_run_all_tests() a bit later in the boot seems\nto have fixed the lockup problem according to Guenter\u0027s limited testing.\n\nNo kunit tests should be broken by calling the built-in executor a bit\nlater, as when compiled as modules, they are still executed even later\nthan this.\n\nFixes: 4e1c44b3db79 (\"kunit, slub: add test_kfree_rcu() and test_leak_destroy()\")\nReported-by: Guenter Roeck \u003clinux@roeck-us.net\u003e\nCloses: https://lore.kernel.org/all/6fcb1252-7990-4f0d-8027-5e83f0fb9409@roeck-us.net/\nCc: \"Paul E.
