Subject: [PATCH v3 0/9] mm, hwpoison: enable 1GB hugepage support (v3)
Here is v3 of "enabling memory error handling on 1GB hugepage" patchset.
I applied feedbacks for v2, thank you very much. Overall design of the
patchset is unchanged. Please see individual patches for details about
changes.
Patch dependency:
- "mm/memory-failure: disable unpoison once hw error happens"
(actually the conflict is not logical one, but adding MF_SIMULATED to
mf_flags conflicts with patch 6/9.)
Previous versions:
- v1: https://lore.kernel.org/linux-mm/20220602050631.771414-1-naoya.horiguchi@linux.dev/T/#u
- v2: https://lore.kernel.org/linux-mm/20220623235153.2623702-1-naoya.horiguchi@linux.dev/T/#u
Thanks,
Naoya Horiguchi
