If you suspect a rwlock problem or a kernel 12 hacker asks for this option then say Y. Otherwise say N. 13 14config DEBUG_RODATA 15 bool "Write protect kernel read-only data structures" 16 depends on DEBUG_KERNEL 17 help 18 Mark the kernel read-only data as write-protected in the pagetables, 19 in order to catch accidental (and incorrect) writes to such const 20 data. This option may have a slight performance impact because a 21 portion of the kernel code won't be covered by a TLB anymore. 22 If in doubt, say "N". 23 24endmenu 25
