Subject: [RFC Patch v2 0/4] mm/mempolicy: some fix and semantics cleanup
Date: Thu, 20 May 2021 16:30:00 +0800	[thread overview]
Message-ID: <1621499404-67756-1-git-send-email-feng.tang@intel.com> (raw)

Hi All,

We've posted v4 patchset introducing a new "perfer-many" memory policy
https://lore.kernel.org/lkml/1615952410-36895-1-git-send-email-feng.tang@intel.com/ ,
for which Michal Hocko gave many comments while pointing out some
problems, and we also found some semantics confusion about 'prefer'
and 'local' policy, as well as some duplicated code. This patchset
tries to address them. Please help to review, thanks!

- Feng


Feng Tang (4):
  mm/mempolicy: skip nodemask intersect check for 'interleave' when oom
  mm/mempolicy: unify the preprocessing for mbind and set_mempolicy
  mm/mempolicy: don't handle MPOL_LOCAL like a fake MPOL_PREFERRED
    policy
  mm/mempolicy: kill MPOL_F_LOCAL bit
