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

  mm/mempolicy: don't handle MPOL_LOCAL like a fake MPOL_PREFERRED
    policy
  mm/mempolicy: kill MPOL_F_LOCAL bit
