[RFC Patch v2 0/4] mm/mempolicy: some fix and semantics cleanup

[Feng Tang]

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@xxxxxxxxx/ ,
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!

    policy
  mm/mempolicy: kill MPOL_F_LOCAL bit
