| 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. | |

| 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". | |
