13 | Mark the kernel read-only data as write-protected in the pagetables, | |
14 | in order to catch accidental (and incorrect) writes to such const | |
15 | data. This option may have a slight performance impact because a | |
16 | portion of the kernel code won't be covered by a TLB anymore. | |
17 | If in doubt, say "N". | |
