lock_torture test failure when lock debug options are enabled. #1045

Open mdchitale opened 1 year ago

When the following options are enabled in the kernel build, the lock_toture test fails. CONFIG_DEBUG_RT_MUTEXES=y CONFIG_DEBUG_SPINLOCK=y CONFIG_DEBUG_MUTEXES=y CONFIG_DEBUG_RWSEMS=y It appears that the test failure is due to the difference in the dmesg output when the debug options are enabled.
