Subject: [PATCH v2 0/2] provide the flexibility to enable KFENCE

Hi, I'm sending v2 about (re-)enabling KFENCE.
I've removed description about use case and just focus on flexibility.

Thanks.

v2:
Take KFENCE_WARN_ON() into account. Do not allow re-enabling KFENCE
if it once disabled by warn.
Modify func names and comments.

RFC/v1: https://lore.kernel.org/all/20220303031505.28495-1-dtcccc@linux.alibaba.com/

Tianchen Ding (2):
  kfence: Allow re-enabling KFENCE after system startup
  kfence: Alloc kfence_pool after system startup
