commit 05f144a0d5 removed vma->vm_policy updates code and it is a purpose of
mbind_range(). Now, mbind_range() is virtually no-op. no-op function don't
makes any bugs, I agree. but maybe it is not right fix.
I dont really understand the changelog. But to restore the policy_vma() is
the right thing to do since there are potential multiple use cases where
we want to apply a policy to a vma.
Proposed new changelog:
Commit 05f144a0d5 folded policy_vma() into mbind_range(). There are
other use cases of policy_vma(*) though and so revert a piece of
that commit in order to have a policy_vma() function again.
