-Subject: [PATCH 236/347] lockdep: selftest: fix warnings due to missing
- PREEMPT_RT conditionals
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
-
-"lockdep: Selftest: Only do hardirq context test for raw spinlock"
-disabled the execution of certain tests with PREEMPT_RT_FULL, but did
-not prevent the tests from still being defined. This leads to warnings
-like:
-
- ./linux/lib/locking-selftest.c:574:1: warning: 'irqsafe1_hard_rlock_12' defined but not used [-Wunused-function]
- ./linux/lib/locking-selftest.c:574:1: warning: 'irqsafe1_hard_rlock_21' defined but not used [-Wunused-function]
- ./linux/lib/locking-selftest.c:577:1: warning: 'irqsafe1_hard_wlock_12' defined but not used [-Wunused-function]
- ./linux/lib/locking-selftest.c:577:1: warning: 'irqsafe1_hard_wlock_21' defined but not used [-Wunused-function]
- ./linux/lib/locking-selftest.c:580:1: warning: 'irqsafe1_soft_spin_12' defined but not used [-Wunused-function]
- ...
-
-Fixed by wrapping the test definitions in #ifndef CONFIG_PREEMPT_RT_FULL
-conditionals.
