Subject: [PATCH v2 0/1] mm/memory-failure: Poison read receives SIGKILL instead of SIGBUS issue
Date: Wed, 24 Jul 2019 16:33:22 -0600 [thread overview]
Message-ID: <1564007603-9655-1-git-send-email-jane.chu@oracle.com> (raw)
Changes in v2:
- move 'tk' allocations internal to add_to_kill(), suggested by Dan;
- ran checkpatch.pl check, pointed out by Matthew;
- Noaya pointed out that v1 would have missed the SIGKILL
if "tk->addr == -EFAULT", since the code returns early.
Incorporated Noaya's suggestion, also, skip VMAs where
"tk->size_shift == 0" for zone device page, and deliver SIGBUS
when "tk->size_shift != 0" so the payload is helpful;
- added Suggested-by: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>
