Subject: [PATCH RFC 0/3] Add a module parameter to adjust kfence objects

This series make KFENCE to be more convenient to adjust parameters in
not only debug process but also production situations. In different
production and development stage, the demands of memory and CPU
limitations for KFENCE is quite different. In order to satisfy these
demands with a uniform kernel release, dynamically adjust KFENCE
parameters is needed.

  kfence: Add a module parameter to adjust kfence objects
  kfence: Optimize branches prediction when sample interval is zero
  kfence: Make test case compatible with run time set sample interval
