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.

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".
