- 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".
