| 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. |

| 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". |
