[PATCH v2 0/2] livepatch: some improvements

[Yafang Shao]

  #1: Clarify klp_add_nops()
  #2: Replace the tasklist_lock with RCU in the KLP transition

v1->v2:
- Enhance the comment in #1 for better clarity and detail. (Petr)
- Replace the tasklist_lock with RCU (Josh)
- Remove the fix for RCU warnings as the root cause is currently unclear.
  Once the root cause is identified, I will submit the fix separately.

v1: https://lore.kernel.org/live-patching/20250211062437.46811-1-laoar.shao@xxxxxxxxx/
