This is actually PATCH v3 for the bug reported in PATCH v2[1], which is
prematurely merged into mainline.

Therefore, this patchset first reverts PATCH v2, and then provides the
v3 fix as the subsequent patch.

[1] https://lkml.kernel.org/r/497d3835612610e370c74e697ea3c721d1d55b9c.1649775850.git.xuyu@linux.alibaba.com

---
v2->v3: replace the BUG to WARN + returning -EBUSY when splitting
huge_zero_page, and keep memory_failure unchanged.

Xu Yu (2):
  Revert "mm/memory-failure.c: skip huge_zero_page in memory_failure()"
  mm/huge_memory: do not overkill when splitting huge_zero_page
