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!

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
