        bool "Read-write spinlock debugging"
        depends on DEBUG_KERNEL && SMP
        help
          If you say Y here then read-write lock processing will count how many
          times it has tried to get the lock and issue an error message after
          too many attempts.  If you suspect a rwlock problem or a kernel
          hacker asks for this option then say Y.  Otherwise say N.

config DEBUG_RODATA
       bool "Write protect kernel read-only data structures"
       depends on DEBUG_KERNEL
       help
         Mark the kernel read-only data as write-protected in the pagetables,
         in order to catch accidental (and incorrect) writes to such const
         data. This option may have a slight performance impact because a
         portion of the kernel code won't be covered by a TLB anymore.
         If in doubt, say "N".
