-             vma->vm_flags &= ~VM_MAYWRITE;
+             vm_flags_clear(vma, VM_MAYSHARE);
      }

I think it should be:
        s/VM_MAYSHARE/VM_MAYWRITE/

I added the fixup.  Much better than resending a seven patch series for a
single line change.  Unless you have substantial other changes pending.

Thanks! That sounds reasonable.

I'll also need to introduce vm_flags_reset_once() to use in
replacement of WRITE_ONCE(vma->vm_flags, newflags) case. Should I send
a separate short patch for that?

That depends on what the patch looks like.  How about you send it
and we'll see?
