Enable lightweight spinlock checks


Linux Kernel Configuration
└─>Enable lightweight spinlock checks
In linux kernel since version 6.4 (release Date: 2023-06-25)  
Add checks with low performance impact to the spinlock functions
to catch memory overwrites at runtime. For more advanced
spinlock debugging you should choose the DEBUG_SPINLOCK option
which will detect unitialized spinlocks too.
If unsure say Y here.
