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". endmenu
